I was driving and it quit. Checked the fuses and found Ecu fuse blown. I replaced the fuse and the "check engine light" came on. Connected scan tool retrieved code 41. I found it charging a low voltage of 12.4volts. I replaced the alternator and still it was giving me a low voltage. What could possibly be wrong? Hammer Time Ultimate Carjunky / Moderator Jul 1, 2009, 9:59 AM Post #2 of 3 (1477 views) Re: 1995 caravan low alternator voltage Sign In The first thing you want to do is test for power on the big terminal of the alternator with the engine OFF. That tests for the inline fuse. If you have power there, then you likely have a bad computer since the voltage regulator is built into it but by all means, have it diagnosed properly before replacing a computer. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

That was a poor design incoorperating the regulator into the PCM... gee those things never go out There is a regulator kit available that splices into the wiring harness for the PCM.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
