headlights and dash lights surging between normal and getting a little brighter
Last night on my 2000 Chevy Tracker 2.0L the headlights and dash lights started to surge or flicker between getting a little brighter and normal. I am going to check the alternator but if it is not doing the problem when i check it then it wont tell me anything. Has anyone else had a problem like this?
Thanks
Thanks

was it your alternator?
My battery was not being charged correctly, so I rebuilt the non-rebuildable alternator, epoxied the stator windings (they were nasty condition, after only 100k).
Alternator testing in-vehicle had said bad diodes, then bad on the bench-test too. So I got a new unit IMR7581, I believe it was. Although my old diodes tested fine when I did surgery on them afterwards.
Anyway, my alternator's working finally.
gotta say, compared to many others, it's a pleasure to remove the alt. in this truck!

I bought a 2003 Tracker that was doing the same thing - pulsating lights. I replaced the alternator and all was well! I've read that many of the refurbished alternators are not any good so I went for a brand spankin new one and my problem was solved. The new one cost less than a hundred bucks at that - less than the rebuilt ones I saw.
