Battery light on


Recommended Posts

Got home tonight, disconnected the exciter wire and started the engine. The exciter wire was 12.4v (the same as the current battery state) so that sort of rules out any wiring issues with the car.

I ran a bulb on a bit of wire between the main charging connection and the point you connect the exciter wire to, and the bulb lit up. This makes me think it is an internal alternator fault, as going straight from the charging connection to the exciter connection should make it charge.

May I suggest removing the bulb

The battery light is part of the alternator excitation circuit, if you take it out the alternator does not work anymore.

 

Most likely there is a problem with one of the (rectifier) diodes in the alternator.
