Working on a TN65 that is not charging. Would anyone have a wiring diagram for the charging system. There is a relay looking box mounted right behind alternator that I'm no familiar with and I'm not sure if it has anything to do with the charging system. Thanks!
You can see the box behind the alternator
if that's a Lucas style alternator, it's just like any other internal regulator alternator, except they sometimes have several B+ terminals, the sense and excite terminals are just the same as a delco, or denso, etc. Just have to figure out which is which by checking voltage with the key off, then the key on, then running.
If your alternator is like the New Holland version below, then the regulator bolts directly to the back of the alternator. The brushes are contained in the regulator like the picture shows.
