What causes the oil light to flash in the Mingtu?
1 Answers
The flashing oil light in the Mingtu is due to common faults in the low-voltage circuit and high-voltage circuit. Common causes of low-voltage faults: Insufficient battery charge; poor or incorrect wiring connections; poor battery grounding; damaged distributor or Hall sensor; damaged ignition switch or poor wiring connections. Most diagnostic methods for low-voltage circuit faults involve using an ammeter or voltmeter to check each wire sequentially to eliminate the fault point. High-voltage wire detachment or leakage; cracked or punctured distributor cap; burnt or punctured distributor rotor; excessive or insufficient spark plug electrode gap; excessive carbon buildup on spark plugs; damaged spark plug insulator; damaged ignition coil or disconnected wiring. Common causes of high-voltage faults: Most high-voltage circuit faults are diagnosed using the high-voltage spark test method. This involves removing the central high-voltage wire from the distributor or a cylinder's high-voltage wire, placing the wire end 3-6mm away from the engine block, and starting the engine to test for sparks. A strong spark indicates that the ignition system is working normally. Methods to reset the engine fault light: Start and turn off the vehicle three times consecutively; disconnect the negative terminal of the engine battery, wait for 30 seconds, and then reconnect it.
