Description

METHOD AND APPARATUS TO TEST THE CHOKE POSITION DETECTOR FIELD OF THE INVENTION The present invention relates to test harnesses and test methods used in test harnesses to determine continuity in the wiring of a vehicle choke position detector and if the choke position detector receives the proper voltage.

BACKGROUND OF THE INVENTION The diagnosis of malfunction or failure of a vehicle has become extremely difficult with the emergence of computer-controlled vehicle engines. This is particularly true in the determination of a fault associated with the choke position detector. As is known, the choke position detector is connected to the electronic control system of the vehicle by means of a removable wire harness. In this way, the malfunction or failure of the choke position detector can be caused by any of the following possibilities and / or the combinations thereof: defective connectors in the harness; faulty wiring; malfunction of the position detector of the P1727 / 98 X choke and / or malfunction of the electronic control system of the vehicle. The diagnosis of malfunction or failure is also complicated by the fact that the failure behavior provides very little information, if any, about where the malfunction exists within the system. In this way, a technician is required to discard each of the aforementioned possibilities and determine the source of the malfunction. When the malfunction of the choke position detector is evaluated, a technician generally determines the wire harness components first. That is, the technician must determine which of the harness conductors is the voltage supply line, the reference voltage line and the ground. The location of each of the components of the cable harness may vary depending on the vehicle, engine and year of the model and the different locations, usually they are too numerous to remember. Then, to establish where the fault exists, the technician is required to use temporary fasteners / testers to interconnect the system's test unit with the different needles / plugs of the wire harness. By doing this, P1727 / 98 X can cause many potential problems. For example, wire harness needles / plugs may be damaged by a forced connection or by a less than ideal connection, or the motor's computer circuit may be damaged if the wires are improperly crossed or grounded. Thus, the technician must be very careful, which makes the time devoted to the task undesirably long. U.S. Pat. of Colborn No. 4,567,756, discloses an engine control systems analyzer comprising a control box of basic test switches that can be connected to a voltmeter / ohm etro. The control box can be used to test the choke position detectors. The control box includes a plug receiver (56) and a multi-pin connector (59), and can be adapted from one vehicle to another by placing and attaching the appropriate cable connecting the receiver and / or the control box connector with that of each of the different makes and models of cars. There are some disadvantages associated with the removable connection cable test unit of the Colborn 75ß patent device. This device consists of a rather complicated circuitry, whose manufacture can have a high cost. In addition, the receiver (56) and / or the connector (59) can wear out and / or be damaged by removal P1727 / 98MX and repeated insertion of the harness (s) for a particular vehicle. Also known are devices for testing circuits and vehicle components for functions other than detecting the position of the choke. U.S. Pat. No. 5, 168,238 from Larance exposes a circuit tester for the fuel injectors of a vehicle. The tester comprises a housing (12) having a pair of electrical circuit connection cables (14, 16), which extend from opposite ends thereof. An amplifying unit can be mounted removably in the housing, which allows the user to observe at a distance the illumination of the L.E.D. U.S. Pat. No. 5,208,543 of Albinia exposes a tester for motorized antennas for vehicles. The tester includes first and second harnesses (30, 32) that extend outwardly from the housing (34). A fiber optic cable can be used for remote observation of the illuminated diodes. Neither Larance nor Albiniak expose, consequently, voltimeters / óhmmetros or connectors to test detectors of position of the choke. Therefore, what is desired, is a test harness that facilitates the diagnosis of malfunction P1727 / 98MX of the choke position detector, which uses simple circuitry and is, therefore, economical to manufacture, which is not subject to wear associated with the insertion and repeated removal of different wire harnesses for each different vehicle, and which includes connectors that can be used with any standard digital voltmeter / ohmmeter.

It should be noted that for clarity purposes, all components and parts of the test harness 10 may not be shown and / or marked on all drawings. As used in this description, the terms "up", "down", "bottom", "top", etc., refer to the test harness 10 when it is in the orientation illustrated in Figure 2, although it must be recognizing that the test harness 10 may be in any orientation when in use, the orientation illustrated in Figure 2 is not necessary for the operation. With reference to Figure 2, a conventional automobile (not shown) consists of an electrical harness 12 extending from the electronic control unit 14 of the automobile. The harness 12 ends in a connector 16 in P1727 / 98MX a known form. The harness 12 can be connected with a second electric cable 18 through the coupling connector 20. The cable 18 is attached in a manner known in the art to the cardanger position detector 22. When the test harness 10 is in use, it is operatively connected between the connector 20 of the choke position detector 22 and the connector 16 of the electronic control unit 14. It should be understood that the complete unit, wherein the connector 20 of the cable 18 is connected to the connector 16 of the harness 12, is of a conventional and well-known construction and does not constitute part of the present invention. Rather, the present invention is directed to the test harness 10 which is removably inserted between the connector 20 of the cable 18 and the connector 16 of the harness 12, in the manner indicated by the arrows in Figure 2, to prove that the voltage is received in an appropriate manner by the choke position detector. As best seen in Figure 5, the test harness 10 sometimes referred to herein as a double ended test harness, comprises the card 24. The card 24 can be made of any suitable material, such as plastic. Card 24 is relatively small, when compared to the units P1727 / 98MX test of the prior art. In the preferred embodiment, the card 24 is approximately 1H "wide, 1 3/8" long, and approximately "deep" With reference to Figures 2-5, the test harness 10 also comprises a first cable 26 having at least two opposite ends 28 and 30. The end 30 is connected to the card 24 and the end 28 terminates in the connector 32 and is operatively attached thereto The connector 32 of the first cable 26 has the dimensions and form for removably connecting with the connector 20 of the choke position detector (FIG.2) The connector 32 can be any appropriate connector known in the art, as long as it establishes a sufficient electrical connection with the connector 20 of the detector 22 of choke position, the appropriate connectors include plug-type connectors, plug-type connectors and multi-needle connectors. In the preferred embodiment, as shown in Figures 2-5, the connector 32 of the first cable 26 is a female-type connector, or is a plug-type connector. Referring again to Figures 2-5, the double-ended test harness 10 also comprises a second cable 34 positioned opposite the first cable 26 on the card 24. The second cable 34 has at least two opposite ends 36 and 38. As you can see better in P1727 / 98MX Figures 3 and 4, the end 36 is connected to the card 24 and the end 38 terminates in the connector 40 and is operatively attached thereto. The connector 40 of the second cable 34 is the complement or pair of the connector 32 of the first cable 26. The connector 40 can be any appropriate connector known in the art, as long as it establishes a sufficient electrical connection with the connector 16 of the unit 14 of electrical control. Suitable connectors include plug-type connectors, plug-type connectors, or multi-pin connectors. In the preferred embodiment, the connector 40 of the second cable in a male or plug-type connector. As can best be seen in Figure 5, both cables 26 and 34 comprise multiple wires within them. More specifically, each cable 26 and 34 comprises a voltage supply line 42, a reference voltage line 44, and a ground line 46. The continuity between the cables 26 and 34 is provided by supplying the corresponding lines to the card 24. That is, the line 48 on the card 24 is a voltage supply line, the line 50 is a reference voltage line , and line 52 is the earth. The voltage supply line 42 typically supplies a predetermined amount of P1727 / 98MX voltage, approximately 12 volts. Each of the multiple wires 42, 44 and 46 may be of any suitable material known in the art, but is preferably 18-gauge flexible wire. Again, with reference to Figure 5, on card 24, so minus two terminals 54 and 56 are mounted and electrically and operatively connected between the wires of the first and second cables 26 and 34, respectively, to connect the card 24 to a digital voltmeter / ohmmeter (not shown). As shown in Figures 3 and 5, a terminal such as 54, is marked as positive and a terminal such as 56, is marked as negative. A terminal, e.g., positive terminal 54, is electrically and operatively connected to power the voltage line 48. The other terminal, the negative terminal 56, for example, is electrically and operationally connected to the reference voltage line 52. The test harness 10 further comprises the light 58, which is mounted on the card 24 and is electrically and operatively connected between the wires of the first and second cables 26 and 34 to determine and indicate in visual form if the electronic control unit sends the appropriate voltage to the choke position detector. The light 58 can be any suitable visual indicator such as a light emitting diode (L.E.D.), commonly known in the art. He P1727 / 98MX light emitting diode 58 has an anode 60 and a cathode 62. Resistor 64 of approximately 150 ohm, watt, connects one end to voltage supply line 48 and the other end to anode 60 of L.E.D. 58. The cathode 62 of the L.E.D. 58 is connected to ground 52. As shown in Figure 6, another preferred embodiment is referred to herein as the wire harness with multiple ends and is generally designated with the reference numeral 10a. The construction of the multi-end harness 10a is essentially identical to the construction of the harness 10 of double end wires, where the equal elements are identified with equal numbers with a suffix letter, the exception of the construction resides at the ends of the first and second cables 26a and 34a. The first cable 26a has one end 30a connected to the card 24a and a plurality of other ends 28a, 28b and 28c, for example. Each of the other ends 28a, 28b and 28c terminate in a different connector 32a, 32b, 32c and are operatively connected thereto. Each of the different connectors 32a, 32b and 32c of the first cable 26a has the dimensions and the shape to be removably connected with a connector 20 different from the choke position detector such as 22 (FIG 2) Referring again to Figure 6, a second P1727 / 98MX cable 34a has one end connected to card 24a and a plurality of other ends 38a, 38b and 38c, for example. Each of the other ends 38a, 38b and 38c end in a different connector 40a, 40b, 40c and are operatively connected thereto. Each of the connectors 40a, 40b and 40c different from the second cable 34a has the dimensions and shape to be coupled with any of the different connectors 32a, 32b and 32c of the first cable 26a. For example, the connector 32a of the first cable 26a is the complement or pair or for the connector 40a of the second cable 34a. Similarly, connector 32b is the pair or complement for connector 40b, and connector 32c is the pair or complement for connector 40c. It should be understood that the cables 26a and 34a may have as many ends and connectors as desired. For purposes of illustration, only three connectors have been shown at each end and there is no intention of limiting them. Also, it is to be understood that the multi-end harness 10a comprises at least two terminals 54a and 56a mounted on the card 24a and electrically connected between the wires of the first and second cables to connect the card with a digital voltmeter / ohmmeter, in the same way as described before with P1727 / 98MX with respect to harness 10 of wires for double end test. It should also be understood that the card 24a comprises a light 58a mounted thereon and electrically connected between the wires of the first and second cables 26a and 34a to determine and visually indicate the continuity of the choke position detector wiring and Verify that the choke position detector receives the proper voltage, in the manner described above. Due to the conventional practices of automobile manufacturers, it is common for different car models and brands to have a different choke position detector connector, such as 20. See Figure 2. Advantageously, because the harness 10a of multi-end test (Figure 6) comprises a plurality of different connectors 32a, 32b, 32c, 40a, 40b and 40c, the multi-end harness 10a can conveniently be used to test a variety of different choke position detectors, without require the technician to commute the test harnesses with each car. Therefore, the multi-end test harnesses 10a provide a labor-saving method and time to test the choke position detector of a variety of different automobiles.

P1727 / 98MX The method for testing the double-ended test harness 10 in accordance with the present invention generally consists of the following steps. First, with the car off, the technician disconnects the connector 20 from the detector 22 of the choke position of the connector 16 of the electric control unit 14. Second, the technician installs the test wire harness 10 when connecting the connector 32 of the first cable 26 to the connector 20, and when connecting the connector 40 of the second cable 34 to the connector 16. See Figure 2. After the harness is properly connected, "the technician turns the car on If the green light 58 is turned on (Figures 3 and 5), the technician understands that the electronic control unit 14 (FIG 2) is sending the supply voltage in an appropriate manner to the choke position detector 22 and that the connections and wiring are satisfactory.If the LED 58 remains off, the technician checks the connections of the wire harness 10, and the connectors 20 and 16 of the choke position detector and the unit electronic control, 22 and 14. The technician then operatively connects the digital voltmeter / ohmmeter with the terminals 54 and 56 on the card 24, reads the start voltage and compares it with the as acceptable with the specifications of the P1727 / 98MX manufacturer. If the amount of voltage presented is not within the limit recommended by the manufacturer, then it must be adjusted; otherwise, the performance of the motor may be less than desirable. Then, the technician conducts a change of the choke position detector 22. This is achieved by moving the choke from a closed position to a fully open position (W.O.T.), that is approximately a negative voltage to five voltages, depending on the make and model of the car and the manufacturer's recommendations. If the voltage indicated by the digital voltmeter / ohmmeter varies in a linear fashion, then the technician can assume that the choke position detector 22 works properly. If the voltage does not vary in a linear fashion, then. the technician must assume that the choke position detector 22 is failing and must be replaced. It should be understood that the manner and method of using the multi-ended test harness 10a is essentially as set forth above, with obvious modifications due to the multiple connectors 32a, 32b, 32c, 40a, 40b and 40c. Therefore, the present invention provides a new and useful apparatus and a method to test the continuity of the wiring of a choke position detector and to determine whether the position detector of the choke P1727 / 98MX choke receives the proper voltage. In this way, it is to be understood that the test harness 10 and 10a provides many advantages over the test analyzers of the prior art. For example, the prior art device 100 (Figure 1) comprises a basic test switching control box 102. It can be adapted from vehicle to vehicle by means of a removable cable 104. However, the prior art device 100 is disadvantageous due to its complicated circuitry, which can be expensive and slow to manufacture, and because the receptacle 106 and / or connector 108 can wear out and / or be damaged by repeated removal. and the insertion of appropriate harnesses. Advantageously, the harness 10 and 10a overcome the disadvantages of the prior art device 100 by providing the cables 26, 34, 26a and 34a, respectively, which are connected to the card 24 and 24a. Another advantage resides in the simple circuitry of the test harness 10 and 10a. The test harness 10 and 10a consists of a voltage supply line 48, line 50 of reference voltage and line 52 of ground. See Figure 5. Two terminals 54 and 56 and light 58 are operatively connected to each other, in the manner described above. Notably, this simple circuitry is all that is required to achieve a test harness P1727 / 98MX appropriate. Another additional advantage resides in the size of the double end test harness 10. The harness 10 extends approximately 12.14", when measured from the tip of the connector 32 to the tip of the connector 40. In this way, the harness 10 is relatively small, lightweight and easy to carry, when compared to the devices of the It should also be understood that the foregoing is illustrative and not limiting, and that some obvious modifications can be made by persons skilled in the art, without deviating from the spirit of the invention. the appended claims, rather than the above specification, to determine the scope of the invention.
