Battery light on

[tower9447]

The battery light came on the other day. I am assuming that maybe the alternator is starting to go. It isnt charging as much as it was. Maybe someone can shed some more light on it.

mine done the same thing. check the connection of the single wire connector on top of the alt. Mine had a short in it. I woumnd up splicing a piece ito it, to make the wire longer.

I checked that and it seemed fine. I will double check it though. I did have to re crimp the large cable that attaches to the back of the alternator. I will double check everything and see. Thanks.

Yeah I would check all your connections. Make sure there isn't any corrosion and they are all tight.

Tower, make sure you check not only the alt connectors but also the wires. The heater hose tends to rub on them and wear through the insulation, causing the battery light to come on.
I had the same problem: connectors are good but one wire was rubbed through.

Guys, I'm experiencing the same thing. I replaced my alternator and have had the batteries on a battery tender for the last 2 days. Not sure what's going on with it...

My light flickers off and on. I just replaced both batteries (only paid $50 for BOTH... an auto parts store was going out of business)

Light flickered less with the old batteries, but seems to do it more now. Old Battery was coroded, but I cleaned that all off when changing them out.

One thing I noticed is that the neg side of passenger battery seems smaller then the others... I tried clamping the connector to "make" it smaller, but it still is a little loose. I dont have the battery tie downs on there (truck did not have them when I got it) but the lights come on more so when it is sitting still than when it is moving.

Is there a way to make that connector tighter without replacing it or a sleeve to put over the batt terminal?
