Scully Posted June 27, 2019 Share Posted June 27, 2019 This is a strange one, maybe someone has come across similar before. The alternator doesn't provide a charging voltage unless there is a high electrical load on the car i.e headlights. At idle or higher rpm - no charging at all With headlights on - constant 14.4 charging voltage throughout rpm range. So the actual alternator works but with regards to the regulator, I didn't think it could just not provide a voltage at all. My understanding is that the diodes in the regulator just maintain the upper limit for voltage output. What are your thoughts? Just to add, all grounds tested ok, no fault lights even when not charging (unplugging the sense wire DOES provide a fault message) Quote Link to comment Share on other sites More sharing options...
