Seems like your alternator is going out.

alt is brand new...wouldnt thew lights get dimmer if that was the problem not brighter...also before the battery light comes on it kind of hesitates when you step on it then you hit about 4k rpms and it feels like vtec when the battery light comes on....

 

voltage regulator?

 

Check your ground wires. Be sure all 3 of them are tight

 

voltage regulator...where is that located....3 ground wires?....i know 1 from the battery to the body...from the front of the engine to the body and im not sure where the 3rd is...enlighten me plz

 

voltage regulator, if im not mistaken, is inside the alternator. it IS possible to get a bad alt. from the start. have it checked at a reputable alternator shop... first i would just meter the car while running, have someone rev the engine while you read it at the batt. it shouldnt fluctuate much it should be around 14.4v all the time

 

so today i reved the engine past 4k rpms and blew out my headlight bulbs...there is somethign deff wrong....

 

try getting your alt checked out, and consider maybe a ground kit, maybe from NRG.

I'm sorry. That just paints a vivid image.

Isn't that what a vlotage regulator is supposed to prevent?

 

it might be ur starter ground .....if its loose it will spark and wierd **** will dim and ge brighter and all that or ur alt...look at both

Exactley.

The lights get their power from alternator, if theyre getting brighter and brighter. What could cause this?

 

i was looking online and i found a voltage stabilizer...could that help?....i also ordered a ground kit in hope that could solve it and they also look neat...also was thinking im using the alternator off of my stock si engine...since its a sohc alt on a dohc motor that could be screwing with it?
