Generator — Precautions (Opel Ascona C)

1. If you suspect that the charging system is not functioning properly, you must take precautions when diagnosing faults, otherwise you may cause additional damage or even completely ruin some parts that, in principle, could still work and work. The following rules must always be strictly observed in order to prevent possible damage.

2. All generator systems are negative grounded. Even a simple mistake when connecting the battery wires the wrong way can very quickly lead to the generator diodes burning out.

3. Before disconnecting any wires in the system, be sure to turn off the engine and ignition. This will help minimize the risk of a short circuit in the system.

4. Never start the engine with the generator output wire disconnected (red wire on positive terminal).

5. Always disconnect the battery cables from the vehicle's electrical system when using an external battery charging source.

6. Do not use the test connection wires, which could move and cause a short circuit in the nearby contacts. Short circuits can cause more than just blown fuses - they can also cause diodes and transistors to burn out.

7. Always disconnect the battery and alternator output cables before welding on the body using electric welding equipment.
