Lets say i am parked in a parking lot and i have my lights on, well when i push on my brakes to reverse my lights will dim. Or if im parked with lights on and i turn my heat on my lights will dim. or if i press on the brakes with my heat on my heat will slow down...help, anyone??????
Use a DMM and measure the voltage. If it's 12.5v or higher, then you're fine. If by pressing on the brake, the voltage drops below 12.5v, then you might want to have the battery and alternator checked. Some of the auto shops will test them for free.
"Crank the car open the hood that the postive off the battery if the car dies your alternator is bad."
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO that is the stupidest thing you can ever do!!!!!!!!!!!!!!!!!!! if your alternator is fine this will most definatly screw up or even FRY the alternator what you wanna do is take your alternator off take it to advanced autoparts and have them test it.
IMO your alternator is fine, but it cant keep up with your system, you might need to upgrade to an HO alt or buy a kinetik hc2400
If your voltage is dropping below 12 volts your alternator is most likely bad.

That's gotta be one of the dumbest comments I've heard today, quote from bcae1.com:
Warning!
Some people tell you that you can check your alternator by disconnecting it from the battery to see if the alternator can produce enough current to keep the engine running. BAD IDEA! Disconnecting the battery will subject the voltage regulator (and computer and audio equipment...) to significant voltage spikes which may cause an otherwise good alternator to fail. Even if there were no damaging spikes, this test would not indicate whether or not the alternator was good because the engine will easily run with a weak or failing alternator.
