Question about 1993 Dodge Caravan

1 Answer

I reversed polarity on my 93 dodge grandcaravan. The altinator is good. the battery keeps a charge till you run it. Tried wiring from altinator to battery and it ran but noticed the interier light 20 amp fuse was blown and the 10 amp fuse was blown. When the fans got turned on they bogged down the power in the engine. Not too sure where to go from here! can someone explain to me in detail where to look and where to start?

    Wouldn't be a bit surprised if you damaged the regulator (part of your computer) Reversing battery on computer controlled vehicles is often fatal to many modules etc. I have no idea what you mean by "tried wiring alt from battery", but I'd check that regulator first.

I bought an 89 dodge spirit, and it wont keep the battery charged has had multiple new batteries put into it and it also stalls every time its put into gear what could be the problem


Most probably, the AIC stepper motor is bad, one way to kno, is when the engine slows at idle when you swithc on the air conditioner, and the Idle automatioc control does not correct the RPM dropping from the increased load. An engien that does not maintain correct and stable idle cannot maintain the battery charged, but it could have multiple issues.

I just had a new altinator and a battery put on it it will run while the battery has charge but as soon as the batterys juice is gone it wont run unless u have jumpers on it. Took it 2 advance and they...


Sounds like a later model with computer controlling the output and this is faulty ,now one of the wires on the back is for the warning light in the dash so disconnect one of these thin wires at a time to locate the warning light control ,then refit the warning light wire and disconnect the other other one ,now what you do is to run another wire from this terminal to a 12v ignition switched feed in teh fuse box wrap wire around leg refit fuse and with engine running disconnect battery and it should keep running if its working ok as the alternator is now battery sensed and not computer controlled ,easy just like an older car without all this fancy electronics which can and does go wrong

1991 Dodge 4x4 truck altinator will not charge, new altinator, all fuses are good and serkets. Altinator will not charge.


Change voltage regulator. Does the battery take a charge from a charger? If not, replace battery. If it does, then regulator is faulty. If still nothing, return alternator to place of purchase, and have it checked.
