Battery Dying!

[Croatan_Kid]

Well I finally found the culprit and it was just what I thought it was.....a fuseable link! I couldn't see it unless I took the air cleaner off and pulled all the wires from behind the master cylinder. It was the one at the end of the Gen 2 power wire and it burnt when it grounded itself against the alternator bracket. Now I can enjoy and look forward to driving my truck It's kinda embarrasing having to get jumps from people all the time!

Now I'm off to wire up a manual glow plug button.

Figured I'd start here instead of a new thread...

My Rear battery is not charging, reading 12.4 while at idle. The alt 2 is reading 27v, alt 1(driver side) is 14.7v, and front batt is 14.7v. I had auto zone check it for me, and the guy was actually honest enough to admit he had no idea about cucv's. He told me about a shop in town that works on semi trucks and ambulances, so I drove down on my lunch break. I had a mechanic meet me in the parking lot and he told me he used to work on them in the military. Bingo. he did the same test that AZ did and had the same results. He said replace the batt cables, and pointed out a fusible link by the gp relay (connects to + side of rear batt) that was melted somehow. I'll try to replace the link this wkend, hopefully it will do the trick! Tired of changing batteries every other month.
