Charging Circuit
So, I've been having battery issues on my 83 High Sierra. I thought I just had a short to ground and figured an easy fix was just to unhook the neg cable from the battery when it was parked and I'd get to it on spring break ( have a lot of classes currently). Well, the battery got run down nonetheless, so I did a couple tests and figured out a.) the alternator tests fine (I took it in to get bench tested), b.) I don't have a short (my timing light doesn't light up when hooked between the neg battery cable and terminal when the truck is off, and c.) my alternator is definitely not charging my battery (12.5 volts across battery terminals, running or not).
So...do any of you have any insight as to where I should start looking? The connector to the regulator in my alternator is chock full of grease, so i bought a new one and will install it tomorrow, but I have my doubts as to whether this will actually fix my problem. Should I be looking at my battery cables? Any other sneaky spots I might check? The alternator's definitely running the electricity when the car's running, just not charging. Also, my dash voltmeter doesn't read at all. Any help would be appreciated. |

Re: Charging Circuit
Grym: Check the fuse link wires down at the starter "B" terminal where the battery hooks up. Also check all the fuses, especially the guages and Ign fuses. Let us know what you find, jim

Re: Charging Circuit
There is a fuseable link on your firewall, by the brake booster and it has a tendency to burn out. Check this link and see if it is complete.
