Did you remove the battery cables and cleaned the posts and terminals, or did you just chemically clean the posts?

A lot of problems on old stuff is fixed with good clean metal to metal battery connections, on both ends of the cables. Gene


Thanks for the suggestions. I will try and check the grounds tomorrow. I checked for continuity, resistance, and voltage drop between the battery and the fuse/relay box under the hood and everything checked out fine. I physically cleaned the battery posts and terminals. I don't think the issue is at the battery, but a ground problem at the relay boxes sounds like a possibility.

Some see the glass as half empty, some see the glass as half full. I just drink straight out of the bottle.
