Voltage

[darkcrave]

Im not sure if its my battery, or my alternator.

But i can not leave my car off with the light on for more then 3 mins, same thing with the radio.
when i turn on my headlights the RPMs drop, same thing with my binkers

what do you guys think

With the engine idling and all accessories off, what is the voltage coming out of the alternator? With lots of accessories on, what is the voltage?

Sounds to me like either the battery is bad or needs to be charged, just take it in to an autoparts store and get them to check it.

i was hitting 13.1 (that's what revscan said) with my car idling, only the radio was on. i think it should be up to about 14 or close.

13-14 volts is normal.

You really need to have both the battery and alternator load tested.
