dash light

The other day I was sitting at the street light waiting and for a brief instant my battery light came on. Thought right off its stalling although the rpms didn't drop any I gave it some gas and it was fine . Well yesterday same thing except my votage dropped down to around 10v so I revved it to aorund 1500 and waited for the light. Made it to work and ran fine on the way home. Checked it this morning and everything seems fine charged good and idles fine. Any ideas on whats deciding to go south on me? Batterys baout 3yrs old.

Belt slipping on your alternator, or alternator's going dead... either those or there's a relay box thingy that Mike mentioned in another post that turns the dash lights on and off when there's power from the alternator or no power... Maybe try a search on that thing...

I'd say check the belt for wear and taughtness, and do the voltage test in the haynes manual on the alternator.
