[0002] A significant portion of malfunctions in 10kW generator systems for wheeled vehicles are due to open circuits in the generator control box or control cables. Therefore, when a generator system fails to function properly, the first step is usually to check for open circuits in the control circuit or replace the generator control box. Currently, the method for detecting open circuits in the control circuit is to use a multimeter to measure continuity, which is slow and inaccurate. Utility Model Content

[0026] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0027] This embodiment is a tester for the control cable of a 10KW generator in a wheeled vehicle, including a test box and a test socket, and its circuit layout is as follows. Figure 1 As shown in the diagram, the upper dashed box represents the circuitry of the detection box, and the lower dashed box represents the circuitry of the detection socket. The area between the two dashed boxes is the control cable being tested. The control cable lines 7, 8, 10, 11, and 12 are prone to open circuits. The detection box includes a rotary switch. One end of the rotary switch is electrically connected to a voltage regulator resistor, the other end of which is electrically connected to a battery. The other end of the battery is grounded.

[0028] The other end of the rotary switch has six positions: power off, Ub-, Ub+, A-phase, B-phase, and C-phase. Five LEDs are connected in parallel to the Ub-, Ub+, A-phase, B-phase, and C-phase positions, and a five-pin socket is connected in parallel to the five LEDs.

[0029] The Ub- position is connected to pin 5 of the five-pin socket, the Ub+ position is connected to pin 1 of the five-pin socket, the A-phase position is connected to pin 2 of the five-pin socket, the B-phase position is connected to pin 3 of the five-pin socket, and the C-phase position is connected to pin 4 of the five-pin socket.

[0030] The other end of the battery is also connected in parallel to all the contacts of the other end of the rotary switch, and a light-emitting diode is electrically connected between the battery and the rotary switch;

[0031] The battery's grounding point is located between the battery and the second LED.

[0032] The test socket uses a 14-pin socket, and pins 7, 8, 10, 11, and 12 of the test socket are short-circuited and grounded.

[0033] During operation, the five-pin plug of the control cable being tested is inserted into the five-pin socket, and the fourteen-pin plug of the controlled cable is inserted into the fourteen-pin socket. Grounding at one end of the battery is achieved by connecting a wire to the casing; this can be done by holding the casing by hand.

[0034] The short circuit between pins 7, 8, 10, 11, and 12 of the test socket is achieved by soldering and then connecting it to the outside of the test socket. Grounding can be achieved by holding the test socket in your hand, or by connecting the test socket to the 14-pin socket mounting hole of the vehicle.

[0035] When the rotary switch is turned to the Ub- position, a circuit is formed between the two ends of the LED. If the battery has power, the LED will light up.

[0036] At this point, if line 8 of the control cable is not broken, the corresponding LED will light up; if LED 1 does not light up, it indicates that line 8 is broken. Similarly, lines 7, 10, 11, and 12 are tested in the same way.

[0037] The testing box includes a housing with a five-pin socket and a rotary switch. Inside the housing are a battery and a voltage regulator. On the surface of the housing, five LEDs (LED1 and LED2) are positioned near the corresponding positions on the rotary switch. The specific electrical connections of the testing box are as follows: Figure 2 As shown, in addition to what has been explained in the circuit diagram, the structural components also include: a rotary switch including a mounting plate 1, a rotary shaft 2 rotatably connected to the center of the mounting plate 1, and a metal connecting bridge fixedly connected to the rotary shaft 2.

[0038] Near the edge of the mounting plate 1 are installed a power-off contact 4, a Ub- position contact 5, a Ub+ position contact 6, an A-phase position contact 7, a B-phase position contact 8, and a C-phase position contact 9; near the outer side of the mounting plate 1 are also installed an arc-shaped mating contact 10; when one end of the connecting bridge 3 is connected to the Ub-position contact 5 or the Ub+ position contact 6 or the A-phase position contact 7 or the B-phase position contact 8 or the C-phase position contact 9, the other end of the connecting bridge 3 is connected to the mating contact 10;

[0039] The mounting plate 1 is also equipped with an arc-shaped strip-shaped electrical display contact 11. When one end of the connecting bridge 3 is connected to the Ub- position contact 5, the Ub+ position contact 6, the A-phase position contact 7, the B-phase position contact 8, or the C-phase position contact 9, the connecting bridge 3 is also connected to the electrical display contact 11.

[0040] The technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
