Re: Battery light stays on
There was a recall in 1985 for the aux battery relay according to Alldata. I am curious if the light is on all of the time, or does it go out as your RPMs go up while driving. Another question I have - is your battery having trouble holding a charge? Is it the only warning light that stays on? I would check your chassis grounds from your battery to your truck body and to the engine. If your stated repairs were done properly, it sounds like a harness or wiring issue.

First thing to do is to test the battery. Do this by turning on the lights or radio and then try starting it. If the battery is weak when you try to start it the lights will dim or go out completely. If so replace the battery. If the lights stay bright the problem is probably in the solenoid or starter itself. The clicking you are hearing should be the solenoid on the starter trying to engage and most likely doesn't have enough power in the battery to start the car. If you are not mechanical or don't have the right tools you will have to find someone to replace the starter and solenoid. If you end up only changing the battery make sure to hook battery jumper cables or a battery charger to the cable connections to retain power to the car when you remove the battery. This is so your radio doesn't have to be reset by entering the code to the radio. If you don't have a charger or jumper cables, then make sure you have the radio code to reset your radio before disconnecting your battery or you will be disappointed when the new battery goes in and your radio keeps asking for you to enter the code and it won't work.
REPLACE BATTERY CABLES THE POSITIVE BATTERY CABLE COULD BE SHORTING TO GROUND.REPLACE STARTER SOLENOID IF NOT BEEN REPLACED.BESURE TO PLACE BACK FLEXIBLE CONDUIT THAT GOES AROUND POSITIVE BATTERY KEEP FROM SHORTING TO GROUND. LAST TIME I SEEN BATTERY CABLES OVER HEAT WAS EITHER STARTER AND SOLENOID SHORTING OUT OR VERY LOOSE BATTERY CABLES CONNECTIONS. REPLACE BATTERY CABLES IF THEY ARE MELTED HAVE STARTER CHECKED OUT YOU COULD HAVE FAULTY STARTER STILL.
CHECK ALTERNATOR OUT PUT SHOULD BE 13.5 VOLTS TO 14.5 VOLTS.IF NOT ALTERNATOR IS NOT CHARGING BATTERY.CHECK ALTERNATOR FUSE AND CHECK ALTERNATOR POSITIVE FEED WIRE AND VOLTAGE REGULATOR WIRES.IF ALL IS GOOD ALTERNATOR NEED TESTING AND REPLACED.IF ALTERNATOR GOOD BATTERY CABLES COULD BE OLD CAUSING POOR GROUND AND HIGH RESISTANCE IN POSITIVE CIRCUIT. STARTER SOLENOID FAULTY IF NOT BEEN REPLACED.
First replace the starter solenoid on the firewall,it is where the positive battery cable goes too,it is most likely the problem,be sure the battery is not low,and the alternator is charging correctly,low voltage can cause this,but most likely the solenoid.
