Car = Supercharged 94 GSR

So heres the problem...



At night while I am driving I notice that the lights go a little dim. So I usually push in the clutch and rev it a little and they usualy brighten up again. every once in a while though they just go dimmer and dimmer.

Heres what I have done already...

I used a volt meter to measure the current while car was on, it reads out 13.68 amps, so thats all good.
I checked the alt. at auto zone, its good.
And I checked all the grounds on the car. They are all good

Any suggestions on what it could be? Reps given to any helpful advice at all as usual.

i had a problem simular to that with a Maxima, i went to autozone they told me that the alt was good and was pushing high 13s, but the car was dying. then i went got a new alt and it fixed the problem. thats just my experience....

No pulleys and the battery is brand spanking new, as in I bought it from Autozone 2 weeks ago

it could still be bad... could've been a manufacturer's defect or something... have it checked as well...

also try rechecking the voltage at the battery with the headlights on with the car idling... the alternator may not be putting out enough while the electrical system is under a load...

Whats up Scotty, Its Ricky, with the Supercharger GSR that you tuned a couple months ago. The car hasn't changed one bit since you tuned it so you may remember it.

the car runs fine other than that? no cel? bring it by so i can connect with the laptop to see if you're losing voltage while driving or boosting. if voltage drops low enough it can affect fuel flow. however, this sounds more like the alternator is going bad or a ground issue.

=the garbage. we only sell/install Interstate. :goodjob:

maybe just a failing alternator. you said its every now and then. so i'd have to say that would be your prob. stay away from that autozone crap
