There is a problem with the power distribution center or the fuse box under the hood. Check all your electrical connections and the condition of the wires and cables. In the meantime, keep charging your battery until you have figured out how to fix the problem. If you don't, you will drain the battery while driving, and when the battery is drained, the engine will die on the spot.

Take a voltmeter to the battery while truck is running. Should read 12.8 to 14,6 volts - that'll prove your alternator is working. My suspicions are your battery is tired and just not holding charge as deeply as it once did.

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.

My brand new alternator wont stay charged


Check the charging relay if working. You can find it in the fuse box which is either in the engine compartment or under the dashboard on the drivers side legroom.

When you turn the key on, does your charge light come on? When working right, the charge light comes on with key on, then when started and alternator is working, the charge light (or battery icon, whatever) will go out. If that light doesn't come on, it may have a burnt bulb or wiring problem, and that will keep car from charging.
If that's alright, you must have a loose connection or wire not connected between your battery and alternator. Also, check your grounds: battery, engine to frame, ECM (likely on top of engine).

It's the alternator...it is not keeping your battery charged. You can remove it and take it to a local parts store and they will test it for free.

BATTERY OVERCHARGED AND ALTERNATOR IS FINE


If you have a fully charged battery when you installed then 14 volts is way to much charge for the battery which would mean that the alternator probably has a faulty regulator and the alternator needs to be changed otherwise you will continue to install new batteries. If the battery was in an uncharged state then it is possible for the alternator to charge at full capacity to charge up the battery.
