I've got some questions, I used a multimeter to check the volts of the alternator when the car was running and was only getting around 9.5 volts and the volts didn't increase when I revved the car up.
I took the alt off and took the alternator apart and cleaned up everything real good and re-soldered the positive pin as best as I could. I put everything back together and put it back in the car.

I started the car and checked the volts, now I'm getting 11.8 volts at idle and about 13.8 volts when I rev the car to 2000rpms with all of my accessories off. Is this normal or do I still need a new alternator? Or should I just go all the way around checking my wires and grounds real good? I'm getting the same reading on the battery terminals as I am on the back of the alt though so I doubt its a bad connection.

 

you should replace the brushes, they are probably worn down... this is mostly what a "rebuilt" alternator is... new brushes.

 

Well I mean that's what I thought to do first, which is why I tore it apart, ya know? They weren't wore down and were actually very clean(compared to other alts I've tore down), the springs were still stiff and neither brush was stuck or anything, I think I'm going to tear it down again tomorrow and also check all of my grounds and everything. I've just never seen a bad alternator give off any volts, no matter how many rpms you gave it ya know, this one gives plenty of volts, you just have to rev it up to get them...
It reminds me of an older domestic type alternator the way it does, is that how these alts are too?

 

We often overlook the heart of the electrical system...the battery. If there was a problem with the alternator,the battery will be discharged. A fully charged battery will have a static charge of 12.5 volts. If less than 12.5 volts, charge it first,then recheck the alternator output.
It sounds like the static voltage of your battery is 11.8 volts,and the voltage regulator is not turning on to field the alternator until the rpm's are increased.

 

Ok, that makes sense busdude, I'll put the battery on charge for a couple of hours and check everything after that! Thanks yall
