Alt only putting out 12v??

Over the past week or so my alt has been slowly putting out less and less voltage......
It went from 14 down to 13, now to 12.....

Is it dead??? Or dying?

Sure sounds like it. Getting an alternator tested is free at almost any parts store I know of, so just drive down and have it checked.

yeah, i thought i was having a battery problem, but got the battery tested and apparently it is fine. it reads 14v when the engine is on, and 12v when engine is off. the thing that is wierd is that when i was doing a compression test, i could only turn it over a few times, and that it wouldn't do it anymore. maybe it is the starter?

but i would say that if it is reading only 12v with the engine running, it is prob the alternator...check the battery too though, if it loses charge over time, then be safe and get that tested too...

It sounds like your Alternator Is taking a dive. Have It load tested...If It's no good - you know what I am going to recommend.

maybe the belt is wearing out and sliping, that's what mine seems to be doing event thow I tighten it quite good.

But then again I bought one from silverrotor (thanks), so ill see what happens when I install the new one.


when belt starts to slip does it mean the alt is goin.

I hate to go over with what I said prior but yes, I still have 10 Single and 10 Double Pulley FD Alternators left.
