ok i got the alt checked at two places and my batt. but my car is charging at 12 even so when i press the brakes or turn the heater on even put down the e brake the car loses volts and dies??? what do i need to do?

 

Does your cars rpm drop really low when you take it out of gear?
Does the car die when its in gear or only when you step on the clutch or have it in neutral?
Whats your idle like?

 

the idle is fine till i start to press the brakes then it get lower and kinda rough. but when i put the ebrake down it dies every time

 

You need to pull out your multimeter and get ups some readings. First you need to check from the positive post to the negative post. It should be between 13-16 volts. Then take your multimeter and ground out the negative lead to the negative battery post. Take your positive lead and check the voltake to the post coming off of the alternator, the one that has an 8mm nut on it. It should also read 13-16 volts. Get back to us with your results.

 

Anything over 15v is bad.

It needs to put out at least 13.6v. 14.4v is the norm.
