Noticed my volt meter was low the other day, measured voltage at the battery with the engine running and was reading aprox. 11.5 which means not charging and it was probably drawing off the batteries, figured the alternator was shot, but went out today and looked it over, started it up and now it's charging fine, getting 13.5 at idle and 13.75 at high idle around 1800 RPM.
I did notice that the belt seems a bit loose, but it doesn't seem to be slipping and it's not squealing or anything, but when I watch it running it seems to be a bit wobble and there is some play in it, also I noticed a good amount of rubber dust on top of the alternator right by the pulley, so I assume the belt is wearing and leaving that dust. Belt looks ok, maybe some slight cracking, but not bad at all.
Does this seem like the alt starting to go or should I try tightening the belt and see what happens?
Thanks.
