Alternator Not Charging?
« on: September 12, 2014, 06:22:28 PM »
Well, My transfercase is back and running.  But i still have a few more issues with the car before it is road worthy again. One is the Alternator is not charging the battery. I can jump the alternator to make it charge, but it won't do it on its own. Im getting the car back tomorrow, But would like to have a place to start when I try to figure it out. All the wires seem to be hooked up.  What should I check for?


Thanks.

Does the alt light come on when you turn the key on? If not, replace the bulb. Power passes through it to the sensor lead on the alt to engage the regulator.

Well now i started it and the battery light came on and the alt is charging. Something is fishy under there. Also the battery cable starts to smoke if the car doesn't start right up. If its cranking its a smokin'.

Sounds like something is shorted to ground somewhere. Have you checked the condition of your wires to see that they haven't rubbed through?

Sounds like corroded cable and more. Negative or positive cable?

I had a cable melt right off the battery terminal once, I was lucky it wasn't a fire. Replace those cables.

It all looks fine, Ill snap some photos of the wiring mess. I want to try to clean it all up but I suck at electrical. There has been many "mods" I think in there. from previous owners. No corrosion, that i see anywhere.

Some previous owners should be drawn and quartered.
