What to Do When Car Circuit Fails?
1 Answers
Solutions for car circuit failures are as follows: 1. Short circuit: Use a wire to temporarily bridge the circuit that may have an open circuit fault, observe the changes in the instrument pointer or the working condition of electrical equipment, and then determine whether there is an open circuit fault in the circuit. 2. Instrument method: Observe the indications of the ammeter, water temperature gauge, fuel gauge, oil pressure gauge, etc. on the car dashboard. If there is a fault, a red light will turn on. If the engine is cold and the water temperature gauge indicates the full scale position without moving when the ignition switch is turned on, it indicates that the water temperature sensor is faulty or there is a grounding fault in the circuit. In this case, it is necessary to eliminate the fault in time.
