The alternator has died on my PCM'd mastercraft. A friend has given me a mercruiser 55A alternator which the output will be fine for my needs as I have no accessories other than a bilge and blower (this is my retro ski boat not my pimped wake boat).
Any how the alternator i removed just had a battery post and a green wire going to +12V switched by the ignition.
New alternator has EXC post and a S post. I think EXC is the exciter which needs +12V switched by the ignition? The S post is maybe the sensor for the regulator so needs to go to as close to the positive terminal as possible?
Am I right guys or is it going to go pop?
