What is the little wire from the alternator for? I'm trying to figure out what the thin red wire coming from the plastic connector on the top of the alternator is for? I accidently clipped it while putting in my motor mounts. I've crimped it back together and my alternator reads 14.3 volts with a digital multimeter, but sometime the gauge inside the dash reads weird. Any help would be appreciated.
p.s. I did not cut the thick wire that connects to the stud on the back of the alternator, just the small wire.

Re: What is the little wire from the alternator for? it tells the alternator when to charge and how much to charge... by changing the resistance you can change how much it charges.. apparently your connection added some resistance.

I heard painless wiring kits has the correct plug and autozone can order it. This for the others I've seen running into this problem and for those in the future. Another member posted that info up for me.
