71 c10 not staying charged... new battery alternator fuses good and new voltage regulator


Maybe it wasn't running long enough to charge up the battery?
Stop trying to jump it, when you are having problems with it dying, take the battery off and have it charged. And/or buy a $20 voltmeter to see what the battery shows. If it says less than 12 volts, it is discharged, and needs charging. A good battery that is not run down should have at least 12.5 volts. A new battery that is charged should have very close to 13 volts, maybe 12.8 volts.
When you have the truck running, check the alternator for charging. You put the voltmeter right on the battery and check it again. This time, with truck running, battery should show at least 13.5 volts. That shows the alternator is working. A good alternator will put out about 13 or 14 volts-the regulator will keep it from going any higher to prevent problems, like a melting battery or electrical parts burning out.
I would say get the charging system working right, then address the problem of dying at stop lights. That could be a carburetor problem, if the alternator is working.

I have a 92 gmc k1500 pickup with a 350 throttle body motor in it we couldnt get the alternator to charge so we cleaned all the grounds and put a new alternator and new battery now its way over chargeing...


either that cable going to the battery is shorted to ground somewhere (maybe on the body of the alternator) or the alternator is defective. there is a chance that you put one of the wires wrong on the alternator and you are forcing it into full field mode. that is a mode we use to test the full output of an alternator. if an alternator stays on full field too long (more than ten seconds) it could fail.

Have 97 acura won't stay charge changed battery


the battery wont stay charged? if youre putting in a fully charged battery and your car runs, but then the battery slowly dies, the problem will be your alternator. the alternator is what maintains a car batteries charge. try replacing the alternator. hope this helps.

Won't stay running


I am guessing that you put in a new battery drove it for a day at most and went out the next day and it wont start. Well if this is true then you will need an alternator, your battery is not being charged. Your car can start a run without this but you wouldn't get that far and eazy way to figure this out is either charge your battery or have a friend jump, be sure to let it charge for 3-5 min. before trying to start.
If it starts than remove the jumper cables and let the car tun for another 2-3 min and turn it off. If you cant restart it than you will need a new alternator
