Excessive wear of alternator pulley causes battery capacity to drop

September 06, 2019

The horse recommended that the wire be fixed and then try normal cutting.

The reason for the above failure is to ignore the connection of the ground wire so that the power line cannot be used as a power system. The starter of the power system cannot be operated due to lack of electricity. Xu Layin, No.15, Changsheng Road, Tangxia Town, Ruian City, Zhejiang Province, China Excessive wear of the pulley caused a decrease in the capacity of the battery. In the early days of production, the battery of the Santana car was insufficient. The battery was only used for 35 days after the battery was removed from the car.

I feel that the battery power is less than 3 is to remove the alternator from the car into the dismantling check to find no short-circuit open circuit. All the signs are normal, maintenance will be re-installed into the car to the turbine generator in order to observe the alternator's power generation, in the output of the armature output series vehicle current decay and then start the engine in the engine after a long turn The finger 6 is 35, and under normal circumstances, when the engine speed is around 1300,1, the current should be a charging current of 1520 people and the battery voltage increases with the charge of the engine. The charging current of the alternator is then increased. Gradually decrease until 0. Obviously the above phenomenon is not normal. Then turn off the ignition switch to stop the engine. In particular, touch 1 to the belt pulley. Feeling hot, so decantation felt that the skin was slipping and causing the AC to slip, and the motor output was carefully checked again from the alternator of year 1;1. It turned out to be a pulley and it was damaged too much. The groove has no effect. The belt 1 contacts the root of the pulley to produce slip. As a result, the alternator output is insufficient. Resulting in battery capacity 1; replacement 1 new skin Lectured after the fault evaluation, Liang Naisheng Heilongjiang Province, Yichun City, the district Ming. 153000 installed relays to reduce the failure rate; then the special point of the children's special pull, the drawing was widely used. And also in the car circuit earth; month 1 it. Shishi Light Relay Relay relay relay relay; etc. Er, during long-term repairs, it was found that many lines of many models were retrofitted with relays to effectively reduce the failure rate, improve reliability, extend the life of electrical equipment, and reverse. Touching some steam to install relays often fails. Such as the 2020 type car is not equipped with headlight relay because mounted on the steering wheel under the variable light open detection often occurs switch wiring heating switch burned phenomenon.

Another example is that the Model D102 tractor has no starter relay at the factory. The line length of the starter is reached after the power supply has passed through the ignition switch and some connectors. Drop people. The burn-out switch contact plus the connector will cause difficulty in starting but a starter relay will be installed if it is a little too small. 1 This will effectively resolve Chen Yong's 601 Box 8620 Troop 46 Unit. 4225 Main circuit ground fault caused by loose bolts. Example 2 The 141 type car was running. The main fuse was blown. The replacement of the main fuse was carried out soon after the main fuse. Dare to find the alternator inside the fixed rectifier. When the bolt is loose, the two radiator plates of the rectifier are short-circuited when the vehicle vibrates, causing the battery anode ground and the total fuse to blow. After re-tightening the bolt, troubleshooting.

The Russian Soviet Union produced spoilers. Close the main switch of Tun Tun. The main fuse is blown.

Ask 3 to drive. After 0, it was learned that the new car was only replaced by the new one. The fuse was replaced first, and then the fire wire on the starter relay terminal was removed and the main switch was closed. The total breaker was no longer blown. It is considered that the fault is detected on the starter relay by dismantling the starting relay. It was found that only bolts were loose on the bottom board of the bakelite. The fixed contacts of the horse's live line rest against the starter relay housing and the starter relay housing is connected to the frame. Causes the starter relay to burn out the main fuse. Correct the fault by aligning and fastening the contact bracket.

In the above two cases, when repairing automobile power system faults during the troubleshooting process, care must be taken to avoid the occurrence of ground faults caused by bolt loosening.
