The Battery Light coming on usually indicates the charging system is not working. If you can limp it down to your local Auto Parts Store they will usually check your battery and charging system for free.
Yes a fuse can cause charging system to malfunction - also there will be a Major Fuse/Fusable Link. If you have your owners manual there will be a section showing fuse locations and description.
Let me know if and how this helps you
Normally the "Fuse-able Link" is right next to the Battery. It'll be a short length of wire supplying all the current to the fuse box.But this won't be the cause.
I have a problem with your description "Battery still dies while driving around". Can you elaborate on this?
Assuming the Battery and Alternator are not defective, the fan belt is tight enough and the Battery is fully charged, all should be ok.
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.
CHECK BATTERY VOLTAGE WITH TRUCK IDLING.SHOULD BE 13.5 - 14.5 VOLTS. IF NOT ALTERNATOR NOT CHARGING BATTERY.IF ALTERNATOR NOT WORKING TO KEEP BATTERY CHARGE.THE TRUCK WONT RUN RIGHT.YOU PCM,CANT FUNCTION AND CONTROL ALL THE ENGINE CONTROL SYSTEMS.YOUR FUEL SYSTEM , SPARK SYSTEM NOT GOING TO WORK IF BATTERY DONT HAVE POWER AND ALTERNATOR NOT WORKING. CHECK ALTERNATOR POWER FEED WIRE AND VOLTAGE REGULATOR WIRES AND CHECK ALTERNATOR FUSE.MAKE SURE ALTERNATOR GETTING GOOD 12.6 VOLTS FROM BATTERY.MAKE SURE BATTERY FEED WIRE NOT BROKEN.
hello mike, how old is the battiry ? you might need a new one if its hot holding a charge , does the car die when your driving it ? could be a bad alternator then or bad tension on the drive belt or a bad belt.also try cleanning the post and the cables that connect to the battery and make sure there tight.
voltage regulator is internal on that alternator. Take the alernator back off
and take it autozone or advance and have them bench test it to see if its
good or not. That model car doesnt have a fuse for the alternator either and
the regulator is internal on that model. Thats a standard sg gm alternator.
those above stores do not charge for testing it for you. another quick way if
you have a volt meter is black end of volt meter to the negative battery
cable and the postive end of the meter to the thick red wire on the
alternator that you had to put the nut on. then with car running that should
show 13 to 14 volts. If not, suspect that alternator. But try the free check
on it before going through too much more grief with that. if you had it
tested. take the whole car to the autostore and ask them to check it while
the car is running, Autozone and advance both have the machine they will take
out to the car and check it for free. Otherwise, get a volt meter and check
it as I said. If the alternator is putting out, then you have a bad cable or
the 'field' wire is bad.
