I've never had my battery light come on when it was dying...and I've been through 2 batteries....grillmasterp said:Get the battery checked out at your local autozone- That way they confirm if the batt is good or bad-
At the same time they can probably check the output of the Alternator or you could check the alternator output with a multimeter - basically should be putting out more than 12V (~14-14.5V I think)
If, after getting everything checked out, it does turn out to be the alternator you might be able to get away with just replacing the brushes inside. My Batt. light came on when mine were worn down, and it costed me about $15.00 and about an hour worth of work to swap them out.Dolemite said:Battery light came on the other day. Sure enough the battery gets weaker as the day goes on. Truck has 53k on it. Is the alt dead, as in don't bother trying to fix it? TIA
Can that pulley on the alt be adjusted?Dolemite said:Turns out it was the 'typical' Yota stuck brushes, 20 minute fix. I can't imagine how all that dirt got in there.
Funny thing is, after putting the alt back in the alt/belt makes a high pitched noise for 1-2 seconds right after starting it.
