1990 dodge caravan,won't keep a charge. Already changed alternator and battery


Either something is draining power from the battery with the key off, or the battery has an internal short.
Have you checked to see which problem exists by leaving the battery disconnected overnight ?

Installed new battery and alternator in 2011 Dodge Grand Caravan and still not charging and killing battery.


I would check all connections. Make the belt that spins the alternator is tight. If you can get the vehicle to an advance auto parts or any tech that can test the battery and charging system that would help. They can all so a see if anything is drawing from the battery this will let you know If there is a problem with something draining the battery

We have a 1993 Dodge Caravan 2.5L L4. New alternator, new battery, new starter, all 7 relays under hood and PCM "one thats in the air intake assembly". Still not charging back up. fine during the...


I have pasted your schematic below. With all new parts, the likely problem is with the wiring. If the car runs OK, the wire with the orange stripe is probably fine. So then you need to check the green wire to the computer for good continuity. Then check the black battery wire and fuse. Finally, check the ground wires. You might try connecting jumper cables directly from the battery to the alternator and turning the lights on to see if good connections make a difference. If they do, then take one off at a time to see which one is the problem (positive or negative).

96 grand caravan 3.3l battery not staying charged. new serpintine belt, batterty, pulleys, and alternator tested ok several times. Also new computer installed and no fuses are blown. Should I replace the...


if alternator tested fine the wire on the back of the alternator is not getting a circuit back to the battery to charge it.
You can run a wire from the back of the alternator to the battery positive post and it will charge the battery.
I have done that several times on dodges because of ammeter gauge in dash being burnt out.
With the ammeter gauge burnt out it breaks the circuit from the alternator to the battery and the battery does not get charged.

1993 dodge caravan, over charging, replace the alternator, was tested and told it was bad, still over charging. Was told that the computer controls the voltage output, do I replace the computer system now,...


The computer has NOTHING to do with the alternator output.
The alternator is self regulating, with diodes, and rectifiers.
If the alternator is over charging it is because your battery is not accepting the charge, so the charger works harder and produces more to charge it, up to a point.
Was the alternator that you installed new or rebuilt ?
It could be another bad alternator.
Please let me know.

2001 Dodge Grand Caravan battery light is on. Battery and alternator have been checked and are ok. What could be wrong?


The alternator has a bad diode in the diode bridge in the alternator,this turns the light on,even though the alternator checks good,and is charging correctly,there is a bad diode,this diode ,along with others,changes ac voltage to dc voltage,if not replaced,it will start causing components to go out.

Sounds like time for new battery, give it a full charge & have it tested, but have alternator checked as well, even though it appears alternator is o.k. because it runs, but just in case it's an intermittent problem with alternator
