I have noticed that sometimes while driving or stop at a light my dash lights dim every once and a while, the same with my headlights, it doesn't dim real bad, but noticable, the car doesn't seem to run abnormal or anything and keeps a good idle, thats why this is realy confusing me, I don't think it could be the battery or the altenator. Anybody else notice this, maybe it's a common thing and normal, but not sure.
I've noticed it too and my explanation is this: I've noticed that it happens when the electric fan kicks on so I think this is what causes the power drain. I don't think it's really anything to worry about.
In today's high technology automotive world, the 12 volt system just doesn't have the juice needed to properly run a new car's electrical system. Be on the lookout for 24 volt systems in cars of the future.
I have a similar problem, but the headlights flash when I turn on the turn signals. I pulled out of a turn last night and the headlights flashed 4 times really quick, then were fine. Is this the start of serious problems or just a finicky switch?
Quick question do any of you with the headlights dimming have an aftermarket stereo??? Because I do and obviously if I turn it up it drains LOTS of power and causes the headlights to dim. Might be a stupid question tho.
It's the factory 6 disc changer, with the upgraded speakers, tweeter package, and factory amp and sub. I've turned the stereo off and it still does it, but it could be a problem with the grounding of the amp or the car itself. I'm going to start upgrading the electrical system, start with the battery and grounding cables. Then I'm going to the big 140 amp alternator and we'll see if that takes care of the problem. If not...I guess I'm going to have to convince the wife that a new uppipe and downpipe and ECU will fix the problem.
