1996 Ford Explorer Q&A
1996 Ford Explorer Question: battery problems
my battery keeps draining completely every 2 days. i replaced the battery. i took the alternator out to get tested and it came back good. i have nothing on in my vehicle when the motor is off. i have no clue why the battery is draining like this. what could possibly be the problem? - cunningham83
in order to find what's drawing on your battery you need 1 small piece of wire (or a close hanger) and a light bulb that you can get from your turn signal or dome light. take off your negative battery cable. put a wire from one side of of the bulb to the battery and the other side to the battery cable. you may need to tape them on. the light will probably light up. touch a 3rd piece of wire from the battery terminal directly to the cable end. the light will probably go off. remove the last wire & if the light stays on you have parasitic draw killing your battery. you can make sure the system works by opening your door to make sure the light comes on. pull fuses until the light goes out. whenever the light goes out you found the circuit with draw. find out what doesn't work with the fuse out & you know whats on the circuit. one of these things is killing your battery. - certified.ase.tech
I had identical problem on '96 EXPLORER. If I let the car sit for more than two days the battery went dead. I used to disconnect the battery if I did not plan on driving the next day. I tried replacing batteries, alternator, etc with no effect. I left the car with a auto electrical specialist and he determined there was a current draw from the sub-woofer in the sound system even with the key off. I had the radio completely disconnected and the problem went away - Visitor
The same thing happened to me this week with my '96 Explorer . Battery light came on, would not go off. But my amp meter is showing that my alternator is doing its job. I left the lift gate open for about 2 hrs and when I went to start it the battery would not turn the engine over. Jumped it and didn't have a problem...but that battery light was still on. If the serpentine were slipping enough to cause the battery light to stay on it would also be squealing non-stop, so I never thought that. I disconnected the negative battery cable and drove it for about 4 miles with no problems, I figured the alternator was not the problem. Installed a new battery from another vehicle, battery light still stayed on. I then got a piece of scotch brite and die-electric grease and disconnected every ground wire and strap I could find including batt cables. Battery light still on. I then had my son sit in the drivers seat and instructed him to let me know if/when the battery light flickered. With the truck running I started wiggling wires and connectors, when I got to the back of the alternator he told me it blinked. I shut it off, disconnected the neg battery cable, popped the connectors off the back of the alternator cleaned and greased all the connectors. Started the truck the battery light was off and has stayed off. - billet1
While driving to work my ABS light came on. Then my Battery light on. Next the panel functions stop working; the wipers were moving very slow on high speed. My radio went out and the headlights ...
then shut off and then I turn on again and it seems ok - I put in a new battery but I dont' know if it is the alternator or what- I don't want to waste money on the alternator if it is something el...
Battery is 12.7 volts static and 14.5 volts when idle. Battery gauge in instrument panel shows zero charge.
Every once in a while my battery light goes on for a period of time
ALTERNATOR WAS REPLACED BUT BATTERY STILL GOING DEAD ALSO IF I DISCONNECT NEGATIVE CABLE ENGINE TURN OFF
