dunno if this is a stupid question or not but im like too tired to think right.

but i was driving and my Brake light and battery light would flicker on and off while im driving maybe i got most likely got a loose connection somewhere but what would make that do that any wire in particular?

Weird, idk why it would flicker... but my brake and battery light came on when my alternator went out... you might want to get yours checked.

i dont think its the alt i think one of the cables is loose or somthing i messed with it today.

the plug felt pretty loose

mine did that on my s13 then it just stoped after 2 or 3 days but i did find "and i dont think this is what was wrong" that the ground was not on good for my fal fans and it burned up the fuse >_<

Mine did that, it was something with the wiring. I forgot what it was. Alternator was fine.

generally whenever that happen to me/someone i know, the negative terminal was loose and or needed to just be replaced.

yea i think the internal volt regulator in my alternator is F'ed the batt light stays on now i changed the ground and still stays on. reason why i think its the internal volt meter is because the alt is Hissing when the car is off and i checked the batt with my DMM and its charging at 15 volts

wow 15v, thats over charging

240smoke

Wait, is it charging at 15V with the car running or is the battery reading 15V?? The battery is actually supposed to be arout 12.8 volts at a steady state.

with the battery, you can't just put a DMM on it, you must check the voltage across the alternator becuase it has an load on it.

240smoke

Well you could if it was disconnected. What is the normal charging range of an alternator?? I thought it was supposed to be a couple volts above 12??

a good system is never below 13.2ish volts. any decent battery can present 12v with an simple DMM however, when you go to crank it, if the cranking amps are not up to it, the car will simply not do anything.

check your fuses batt.
