2001 Chevy S10 charging problem.
My truck just went dead the other morning with no
warning or indication of problems at all. I was
jumped and on my way home when I notice the
battery meter in the truck dropping, radio died and
dash lights gone. Naturally Im thinking alternator.
Took it off and had it tested. Tested good. Battery
tested good. I start checking and cleaning all
connections. Charge the battery and all looks
good. Half way to work and same thing lost
everything. Charged it at work and halfway home
same thing. I barely had headlights at all limping in
the driveway. I hit a good bump and everything
comes back on but right back out. I'm thinking now
got to be something loose. I have checked and
cleaned everything. I'm out of ideas? Help.
Check grounds from engine to frame and battery to frame and look for loose wires and fuses that are not in all the way or part way in not seated fully and check for corrosion inside battery terminal wire insulation. may be a wire cracked inside other wire insulation, set up a meter and move around wire(s) to see if charging cuts out. But I would question the alt test as sometimes its working and may pass test and other times it is not working and drains you battery till it dies. I would test using a new alternator. If it does same thing take it back for a refund.
Thanks my friend. You gave me some new ideas.
