light surging?

[dsm10o0]

I've been having this problem ever since I got the car. All of the lights inside and out surges when in idle. What would cause this? I've been ignoring it but now its getting annoying.

Alternator is going out

I agree with mike, nico , is it a dsm alternator in your car or a gvr4? 75amps vs 90amps and check all your grounds.

Yeah, it's a DSM alternator. Been looking for a 90 amp but if I find one, I don't have cash but if I do I can't find any. /ubbthreads/images/graemlins/banghead.gif

I bought my replacement at Kragen, and its been working for the past year and a half with no problems.

yeah the oreilly/Vatozone ones are pretty decent. and when you get them they come with lifetime warranty's

I have a spare VR4 alt, just pay shipping as it would need rebuilt/refurbished.

had similar issue on my pathfinder, lights would surge, Then they would get brighter as the rpm's went higher. Till it went out.

I had a guy look at it who rebuilds alternators, he said voltage regulator, surging lights, especially in correlation with jumpy idle is a sign of a bad voltage regulator.
