Battery light on dash

Other than a wiring problem, the only thing that will turn the light on is a broken belt (obviously not in this case) or a defective alternator/regulator. I'd suggest looking no further than the connections on the back of the alternator (unlikely) or the alternator itself.

I assume you're sure it's the battery light, and not the low coolant or low washer fluid lights which can go on in the manner you describe when their respective levels are low.

Hi..

Have you managed to solve the battery light problem? I just replaced the alternator!! However the problem remains..i.e. when accelerating the light comes on temporarily. The alternator cost $500 and no solution. let me know what else can be done..

thanks

I have not found anything that appears to be the cause. Replacement alternator for me was a factory rebuild by bosch themselves. As Mike F has pointed out, there are not too many things to point to. I am wainting for it to happen again, and if it does I will reseat all the electricals to the alternator. If that don't do it, I will start thinking it is the alternator it self or the pulley on the alternator possibly slipping on occassion. I doubt it is these things but what else could it be? Yours does it only on acceleration? Mine has done it on acceleration and at steady state highway speeds.

Yow! I think you need to discover $15 junkyard alternators! Actually the only thing I've seen fail on one so far is the regulator which new is about $60. Where'd you buy it from, the dealer?

Have you looked for a loose connection to and from the instrument panel? The battery light is fed by two wires, one from alternator and one from the battery.

All the best, Peter.
