intermitent battery light

[Russ]

The other day the battery light flickered in the dash, then went out for about a week, tonight it flickered a few times. I noticed some corrosion on the battery terminals, could this be the cause? Batteries are 2 years old and the alt. is about 6 months old. Thanks

it wouldnt hurt if you fixed the corrossion, but i dont htink thats your cause.

my alternator did the same thing with the batt light when it was on its way out, kinda "touch and go" before i took it off of life support and replaced it.

Check the alternator wiring for chafing and also check the big lug to the alternator for cracking. Cheers!

As Patrick said check the wires on top of the alt.Sometimes the heater hose rubs the coating off.

I checked the wires all seams good, didn't have time to clean batt. posts. Might be a bad rebuilt alt.

Might be a bad rebuilt alt.

Very good possibility. Last year I went through three rebuilt ones from NAPA on my 75' before they came up with a good one.

Had it checked today. Yep bad alt. I hate this junk rebuilt crap.
