Three. Precautions during maintenance
In order to avoid damaging the AC generator on the car, some precautions must be taken
into consideration regarding the generator assembly.
1) For whatever reason the storage battery is unfixed, the polar connection must be
correct when it is refixed, failing which the unidirectional rectifier may be damaged.
2) When a backup storage battery is used to assist the startup, make sure that the anodes
are connected to each other and the cathode of the backup storaeg battery shall be
connected to the properly working ground terminal on the engine of the car to be started.
3) Do not use a quick charger as the backup storage battery to assist in the startup.
4) When the quick charger is used to charge the storage battery, be sure to detach the
storage battery cable.
5) Do not try to polarize the AC generator.
6) Check if the diode is electrified. Do not test with a load bigger than 12W.
7) Do not create any short circuit or ground circuit for any terminals of the AC engine.
8) Consider the matching between the polarities of the storage battery, the AC generator
and the voltage regulator before making any electric connections with the power supply
system.
9) Do not keep the AC generator circuit open. Make sure that all connections in the
circuit are clean and have a good contact.
10) Disconnect the ground wire of the storage battery during maintenance of any
electrical parts.
11) The storage battery must be disconnected during welding on the car.
