Electrical Issue

[bovey]

Hey guys,

Short version. I'm looking for all the grounds on my '71 GMC.

Long version of this request is below.

Trying to figure out a charging/electrical issue. Originally traced it to the Alternator that had a faulty regular (Single wire conversion) and had it rebuilt. FYI - I witnessed the repaired Alt on a test stand and everything worked correctly.

Anyway, I hooked everything back up tonight and everything seemed fine until I shut the truck off and it would not start. It stated like a champ the moment I put jumper cables on it.

So, there is a chance the battery is toast as it is around 7ish years old.

But I want to check all the grounds. But where all all the grounds, it's been 20 years since I had this truck apart and I can't remember. Obviously, there is one on the engine, but is there any in the cab for the wiring harness?

Should mention that I'm running a Big Stuff 3 in combination with the original wiring harness and a single wire Powermaster Alt.

NOTE: When my shop rebuilt my brand new Powermaster Alternator (only had 7000 miles) - the could not believe how cheap some of the part where in it - given the regulator from Powermaster, they were amazed it ever charged at all.

Thanks in advance,
Bovey
