Quick question about the wiring for my mk1 mx5 alternator.
It has 3 wires, one the main feed to the battery and two others in a multi plug.
I understand one will be a permanent 12v feed for the exciter circuit but the other?
I found this picture.
Which includes a warning lamp however my digi dash can monitor its own power supply and put the light on at any voltage I determine so I wouldn't need that.
So is it fair to say, assuming I've understood the picture I need two 12v inputs (one switched with ignition and the obvious main power output?
