Hey,

My idle also goes up to about 1500 RPM when the battery light is on, but then goes to regular 750 RPM when it turns off. Also after 4000 RPM the battery light turns off. Sometimes it stays on for a while, other times it flickers, its never constant. What could it be? Thanks for any input.

Any idea on the condition of the alternator? This sounds similar to how mine was acting when the alternator died (well, never fully died, but wasen’t putting out enough power). If you have an Autozone around they will run a free charging system diagnostic - I believe the output amperage should be around 40-45 for a good one at 2000 RPM, with the stock 70 amp alternator.

Had the same syptom before my alternator died. Get it checked out before its too late.

Wait, how’d you replace the brushes w/o taking out the alternator?

Oh yeah, I’ve had the similar battery light check and it’s the alternator that needs replacing or fix’n. Go get it checked before the car won’t crank!
