i have seen somewhere the answer to this but i cant find it anywhere. My alternator is giving me 12 volts for charging but only 1 amp. does anyone know the answer to fix this? i think it is the pcm has to be replaced but i cant remember.

 

1) You should be getting 13.5V output as a minimum from the alternator. 14+ is more like it.
2) How do you know you're only "getting" 1 amp?

 

i am getting 14volts from the Alternator but i not getting enough amps to run the truck. i had it tested at autozone and believe that im not gettin the amps the system needs.

 

get a new alternator, they are like $130 and take 15 minutes to replace

 

i dont want to get a new alternator [X(]. i am trying to sell it at the moment.

 

buy the field repair kit to just refurbish it... they sell them cheap for most makes.

 

Slightly off subject, but when my truck is running I am getting the right votage from the alt. (13.5-14.2 normally depending on speed) I know this because I have a radar detector with a digital voltmeter, and when the engine is off I get around 12.4v as I should. However, the voltmeter in the instrument cluster reads 12 while running, and indicates about 10v when not, almost like the normal line was incorrectly marked 12 when it should have been marked 14, or the needle is not calibrated correctly. It has been this way since I bought the truck in 2001. (It's a 1995 model) Is anybody else seeing this?

 

where can i get one of those and what is the name of it .

 

I got same problem with mine. It cost me only $12.04 to fix it.
I replacedND alternator brush assy $7.99 from ebay + S/H.
