Having problems with your 1989 Ford F 350 ?
I have a 1989 f350 dually with a 460 7.5ltr engine. My problem is the battery seems to be holding a charge but when i turn the key on the voltage drops to almost 7 vdc, and therefore not enough to turn over the engine. And i was wondering what is the round thing the battery pos cabble hooked to? it seems to be connected with the alternator as well. I found a frayed and badly decayed wire on this. Maybe this is the problem?
Do a load check on battery. ck cable to starter. ck ground cable. pull starter off and ck starter.
