I already went and read everything about the voltage at mini mopar at least 3 times.
Car is a 85 GLH-T with 89 2.5L, 87 TII 3bar cal, 90amp denso alterantor, etc...
Alterantor was charging perfectly fine at 13.5v, then I changed the pos battery connector, welded the exhaust in, and some other small things that I can't remember. Next time I went to start it, I notice the fan was on right away and the car was running off the battery, below 12v. Code 16, the car says. Revs maked NO difference in voltage out-put. Battery puts out around 12.4v when the car is off, 11.8 when the car is running. I had make sure the battery was completely charged with a battery charger.
Tested the alternator field coil terminals and the voltage is always lower than it should be, according to mini mopar. Tested with 2 alternators, same thing. Test with a known good extra computer under the hood, same thing. Final kick, bought a new connector and new old dodge truck style external voltage reguatlr and set it up as BFnGA said, http://www.turbododge.com/forums/showthread.php?t=83873&highlight=dodge+regulator+voltage, all result in less than 12v when car is running.
Tested the resistance of the alternator pos wire from alternator to battery, fine.
Tested the resistance of the alternator neg wire from alternator to battery, fine.
Checked, doubled checked and trouble checked all positive wires and makde sure I connected them all. Checked the engine ground and body ground. Checked all the fusible links, all the connectors around that area of the car, all checked out fine.
I spent all day today trying to figure out what's wrong and at the end, car was still running less than 12v.
I'm going to the part store to have one of the alternator be tested, but I really don't think the alternators I have are bad.
What else am I missing? This is the ONE last thing preventing me to take the car to emission test and get it register to my name!!! Please help.
