Battery Light coming on in Dash??

My Battery light is coming on every now and then. More times being when my foot is not on the gas, but coasting or on the brake. What is this light trying to tell me??

It is trying to tell you the battery isn't getting enough voltage. Be it the alternator or a fried battery or corrosion, just like he said .

Most likely the alternator though, since that is technically controlled by your foot on the gas or brake.

Lightbulb

Don't get too concerned about the alternator just yet. Pop the hood and check the connection on the top back of the alternator. It may be hard to see as there is a heater hose that routes right over the top of it. Check that wire, because the heater hose itself will actually occasionally knock the wire loose and make the light flicker or stay on, depending on how loose the connection is. This happened on my '95, and when you compare the ten minutes and 3" strip of electrical tape I used to solve the problem to the $250 price tag on a new alternator, what have you got to lose?

That is a good point. I was just suggesting it be something alternator related lol, which that type of thing would be included under. Great tip

Seems like all the wires are intact. And the Alt. looks easy enough to replace. But how do you get that big fat wire off the back of it?? And whats the procedure to loosen the belt. I guess you can tell, I dont have a manual yet. How can I tell if its 110 or 140 volt??

Thanks, Rob

110AMP.....most likely, very few snow plow preps came with 140 but mostly cab/chassis for the builders (ambulance, wreckers, etc.)
