While merging onto an interstate today, jumped on it. Wound it up to65 or 70 and when it shifted, the alternator light came on. No squealing or unusual noises. After a few miles the light went out and have had no further problems. Any ideas?

Cables are both tight. Really weird. Belt is new. It's never done this before. I was congratulating myself because it seems like I got rid of the CELs I'd been having.

If it came on at high RPM, I'd say your belt may have stretched. Just not seating on all the pulleys at higher RPM.

But keep an eye on that alternator, may be a sign of what's to come.

I would say your alternator is on the way out. It might last a couple more weeks or a month, but something is not right in it.

If the alternator's light came on, its voltage output went below or above a pre-set voltage limit. If your battery connections are tight, you may want to check your alternator's diode rectifier.
