View Full Version : charging issues?

12-18-2008, 07:41 PM
so my truck has started acting funny, it runs fine and all, little low on power (electrical power), but itll keep running, only problem is the battery wont charge, (tried a few different batteries)

could the alternator be pooched? it puts out enough power to run the truck but wont charge the battery

Sounds like you answered your own question to me. Likely is pooched.
Or the belt could be slipping(and no there isn't always a noise involved) That will affect your output too. More likely shot though

i know the belt is cracked and old n stuff, but would a belt cause it to do it that bad?

Mine was doing it intermittantly last weekend while i was playin in the snow. It would drop right down to near 8 volts until i stopped and let it idle.
My crank pulley was like a big ice cube so i think my belt was slipping.
So yes a belt could cause it.
Also could be a bad battery cable, i have had ground cables go bad and cause it before. They arent always visibly bad.

Check the alt out put to see how many volts its producing.

I just went through this with my dads truck it was the cable
Like .C.W. said not always visible

i changed the alternator to one that i know works, changed the belts, checked all the positive wiring, if it still doesnt work ill try changing my ground cables

make sure you have clean conections everywhere and your belt is really tight

you can full field the alt. should be an SI type on that chevy. stick a small screwdriver into the back of the alt. there is a spot that looks like a D and if you hit that spot it will put out max power. if it works then your regulator is shot. chances is that you dropped on diode in the tree and you lost 2/3 of your power. feel the pullys to see if the are hot after a few minutes of running. if so the belt is slipping. do you have a big stereo in it? this will take out the diodes! did you run it with out a battery? this will also kill it. so many thing it could be! but I'm not a mechanic! lol

:dontknow: no clue, just changed everything

most likely the alternator, my diesel did the same thing, replaced the alt and it was good to go
