丰田车蓄电池放电（TOYOTA battery discharge） - TOYOTA battery discharge Manufacturer: Toyota Auto Body Co, license plate number: crown E-MS137, engine model: 7MGE type, production year: 1991, mileage: 65000km. Symptom: battery discharge. Troubleshooting: first remove the battery, and then set the charger to measure the current consumption of the vehicle. Load the charged battery into the car and then connect a current meter on the - terminal to measure the dark current consumed by the vehicle. As a result of the measurement, the key ignition switch is placed in the OFF position, and the 1min current is continued to be 1.25A. The current should only last 5S. So this is the cause of the battery discharge. Set the ammeter, put the key ignition switch in the OFF position, wait for 5S, then pull out the fuse and relay in sequence. The dark current drops significantly after the power seat relay is removed. Investigate electric seat circuit, switch short circuit, can not cut off the current of this circuit. Replace a switch and the problem is solved. Return -------------------------------------------------------------------------------- Emergency treatment of spark plug If the spark plug fails on the way, the car will cause hair and the engine will not work properly. If the cause of the malfunction of spark plug electrode carbon electrode gap is serious or wrong, can be excluded by the removal of carbon deposition, adjust the gap, if the spark plug fuse or leakage or rounded shape electrode can not produce spark fault, and the hands and no spare parts, we can according to the following methods of emergency treatment. 1. spark plug next to the electrode burned When the spark plug burns, it does not produce sparks. In this case, the available pliers will carefully bend to the side of the center electrode, and keep it in the 0.6-0.9mm gap can continue to use the edge with the spark plug. 2. spark plug central electrode burn off In this case, the ceramic core of the spark plug skirt can
