How To Re-Polarize Your Dynamo

After leaving your vehicle standing for long periods with a flat battery or replacing your dynamo you may need to re-polarize it. To enable it to charge the battery correctly

1. Disconnect battery
2. Remove fan belt
3. Remove all wires from dynamo
4. Take a length of wire from the battery ''+'' terminal to the ''D+'' terminal on dynamo
5. Take a wire from battery ''-'' terminal to ''D-'' terminal on dynamo, then link ''D-'' to ''DF''.

The dynamo will turn like an electric motor.

6. After 10 secs remove wires, and reconnect original connections.

When converting 6 to 12 volt you will need a new dynamo stand and dynamo backing plate.

When changing from dynamo to alternator you will also need to change the stand and backing plate.
