i dunno if this goes here..but ill try anyways..

recently..my battery light came on..

the thing is...

if i rev it past 4k...the light goes off..but once it reaches under 4k...the light goes back on..

any idea whats going on?

 

Do you have a multi meter. Check to make sure that the alternator is putting out atleast 13.5 volts. The reason it goes out is because at idel the rpm falls and the alternator is not putting out enough voltage and the ecu kicks a code. It most likely the voltage regulator has taken a dump. A new alternator will fix this. Also make sure your belt is tight.

 

how do i tighten it up? :[

im a man that need pictures lol

 

I am taking it that its a "da" 90-93 teg.

 

yeah...now..the light shuts off occassionally..

but when its on...the idle surges a little..
