Car belongs to a friend of mine and had 3 alternators in the back seat when he dropped it off so I knew it was more than an alt issue .I had a pcm from one that he wrecked a few years back so i did swap it in with no change so its back to original pcm car runs fine no light on with this alt but i swapped one of the others in to see if they were bad , voltages were the same but batt and brake light was on dash. i took all 4 units to advance auto and the all checked ok and all maxed at 14.9 which was less than what im getting in car , reinstalled and here i am
Check combination meter.
Testimonial: "do you know where its located"
sorry i just looked at pic you sent , gauge cluster ? if i unplug it could this stop issue, never had a cluster have an alt issue
not sure. Follow the white wire from the alternator.
It's the only thing in the circuit you haven't replaced. Try cutting the white wire. 15.4vdc is actually ok as long as everything works.
I cut whuite wire no change
Ok, I guess that's a good thing. Solder it back together. It's hard to know what the pcm is telling it to do. Since you have tried another pcm, I don't see that as the problem. If everything is working, I would leave it. Otherwise, I would ohm the two wores that go to the pcm. Maybe one has too much resistance. If they are good, the last resort is to modify the design by adding a resistor to the charge wire as it leaves the alternator., and that just seems weird.
any idea on what resistance /ohm should be on those wires
any way to add additional regulator and delete computer as done on dodge products
Should be too small to measure. Less than one ohm. What kind of meter are you using?
I think you can use external regulator, but the computer will throw a code. What symptoms do you have other than the alt light?

eBay has these manuals available. Item # 270544305731
Sells for 6.99 to 7.99 + .99 for shipping.
This is the repair manual and is a CD for use with a PC.
They have owners manuals for some models too.
good luck

Do you mean that the fan does not work on 1,2,3? If so, there's a resistor network (in the switch assembly I think in the 2002) that has failed.
You'll need to remove the fan switch assembly to inspect this. If its broken, locate a replacement at a wrecker.
If the fan does work on all settings, then there's an issue with the AC system, probably low refrigerant level. You may be able to get the system repressurized if the leak is not too severe.
