Hello all. New problem. My battery stopped charging consistantly. When it charges, everything runs great... But for no reason at all, on occasion it will just quit charging like the alternator is bad. Unfortunately, whenever I go to check what's causing it, it starts charging like normal again.
2.8 L Original V6 in 1986 2M6. No electrical modifications.
Checked so far:
Pulled alternator, all connections good and clean/tight. Bench tests perfect at 13.5 - 14 V.
Connector from alternator to battery checks good continuity with ohm meter.
All engine compartment Fuse links to battery fine. All dash fuses good.
Battery tests good and holds charge. Battery connectors fine and clean/tight.
Engine ground including alternator housing is good. Chassis ground is good. Both checked with volt / Ohm meter.
Gauge pod functioning fine, "Volts" light works fine. (The gauge actually works well enough to where it was the first indication of the problem).
Like I say, when it works it's fine. Good strong charge, lights not dim etc. But when it quits charging, it goes quick. Battery discharges rapidly like a dead alternator, and I've barely made it home twice. But then I can't get the problem to repeat itself at home once I get it started again. Very frustrated.
Well, at this point I'm open for suggestions. I can't afford to just start swapping things I don't know to be bad, and you guys always seem to help me find the gremlins. Thanks!
