Glyn Harper Posted June 25, 2018 Author Report Share Posted June 25, 2018 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.

Most likely there is a problem with one of the (rectifier) diodes in the alternator. Quote Esprit Freak Link to comment Share on other sites More sharing options...
Glyn Harper Posted June 26, 2018 Author Report Share Posted June 26, 2018 I'm going to take the alternator off tonight and get someone to look at it for me. I think I've exhausted everything else while it's on the car. 1 Quote Link to comment Share on other sites More sharing options...
