With my recent difficulties (fried off several inches of wire from alternator D+) I thought I'd review the wiring diagram.

I have a Haynes E3 diagram which is likely mostly correct for "basic" stuff like alternator, voltage regulator, starter, etc.

I also have the two Blue Books covering the E9. Section 61 has a ton of wiring diagrams for various iterations and model years, including what seem to be some updates. Is the attached diagram that says "12.71 Addition" in the lower left corner, the correct/latest diagram? I see a "pre-74" diagram in the media section but no mention of an update on it (possibly cropped off).

If the forum doesn't have the diagrams I'd be happy to scan them and provide, with keys to the terminals.

Rob, that thread is 404.

I've been on the list a long time but never gone much further than the Discussion. I did find some stuff in the Media tab, will look further in Scott's material.

At first glance it looks correct. Forum FAQs thread by Chris has several model year wiring diagrams and wiring device legend. Look at attachments here >
