After the horse recommended that the iron wire be fixed, try again and cut it.

The reason for the above-mentioned fault is that the connection of the grounding wire is neglected, so that the power supply line is not a loop, and the power system starter is unable to work because of no electricity. Xu Lai Yin, No. 15, Changsheng Road, Tangxia Town, Ruian City, Zhejiang Province, China, 325204 AC power generation Excessive wear of the pulley of the machine caused the battery capacity to drop. The battery of the Santana brand car that was produced earlier was not fully stored. It was only used for 35 days after the battery was fully charged.

I felt that the battery was low. I removed the alternator from the car and went into the decomposition test to find that the short circuit was broken. All the poles are normal, the maintenance will reload the turbulence generator into the car. In order to observe the power generation of the alternator, only the current of the vehicle is used in series at the output end of the armature, and then the engine is started after the engine is turned away. The finger 6 is 35, and under normal circumstances, when the engine speed is around 1,300,1, the current should be 1520 people's charging current and the battery's voltage will rise due to the charging of the alternator. Gradually decrease until it is 0. Obviously the above phenomenon is not normal. At this time, the ignition switch is turned off to stop the engine, and in particular, the pulley of the wind blower is touched. I feel hot, so I think that the skin is slippery and causes AC, motor output, and again from the year 1; 1 alternator carefully checked. It turned out to be a pulley and it was too much. The groove has no effect. The belt 1 is in contact with the root of the pulley to cause slippage. As a result, the alternator output is insufficient. The battery capacity is 1; after the replacement of a new leather wheel, the fault is judged, Liang Naisheng is located in the south of Yichun City, Heilongjiang Province. 153000 installed relays to reduce the failure rate; the special point of the work is very popular. And the car circuit is also earthy; month 1 it. Such as the Shichang light relay pull port relay starting relay; and so on. Er, during the long-term repair process, it was found that some of the lines of many models were equipped with relays, which effectively reduced the failure rate, improved reliability, extended the life of electrical equipment, and reversed. Dip some steam to install relays and often fail. For example, the 2020 type of car without headlamp relay is burnt out due to the frequent occurrence of the switch wiring of the dimming switch installed under the steering wheel.

Another example is that the 1 D 102 tractor has no starter relay when it leaves the factory. The power supply reaches the starter line length from the battery through the ignition switch and after some connectors. Drop people. Easy to burn out the switch contacts and if the connector is not small, it will cause difficulty in starting but add a starter relay. 1 This can effectively solve the 46 detachment of the 8620 unit of Chen Yong Liaoning Laoshan 601 mailbox. 4225 caused by loose bolts caused by the main circuit grounding fault 2 cases 0 people 141 type car driving in the total fuse was blown off after the replacement of the total fuses, the right to appear in the same place dare to dismantle the fixed rectifier found in the alternator When the bolt is loose, the two heat sinks of the rectifier are short-circuited when the vehicle is running, causing the positive pole of the battery to be grounded and the total fuse to be blown. After retightening the bolt, troubleshoot.

The Soviet Union produced the spleen dump truck. Close the main switch. The total fuse is blown.

Ask 3 to drive. After 0, I learned that the car has recently replaced the starter and replaced the total fuse. Then the fire wire on the starter relay terminal was removed and the main power switch was closed. It was found that the total breaker was no longer blown at this time. It is considered that the fault is removed on the starter relay and the starter is checked. It was found that only the bolts on the bakelite floor were loose. The fixed contact bracket of the horse fire line is placed on the starter relay housing and the starter relay housing is connected to the frame. Causes the starter relay fire line to burn out the total fuse. Troubleshoot after tightening the contact bracket and tightening the bolts.

The above two cases of troubleshooting shall be taken care of when repairing the vehicle electrical system to avoid the occurrence of loose ground caused by the loosening of the snail, but the part of the grounding iron shall not be grounded but may affect the normal operation of the vehicle.
