So I ran a new wire and put the old alternator in to see and It ran good for about 1 hour then the car shut off again. I barlet made it home. So the next day I go to drive it and it ran fine but I only drove it in 20 minutes or so periods just going places though out the day. Then I drive it longer an in a hour or so it cut off again. I am using the same alternator with a new fuse and wire run So I figure its a bad alternator also it seems the alternator kinda gets hot still so I am thiking its over heating and the car kills then cool an the car runs fine. Well today ?/I get the alternator checked at autozone and it checked out ok. But The alternator test only was for 30 seconds at a time an it was about 5 times.

Is it possible it would check out fine because its not running long ebough on the test. and is bad but only when it heats up after a while?
I dont want to buy a new alternator if I dont have to. Also the heater seems to make it kill faster meaning more of a pull on the alternator. acually any electronic device when on in the car seems to make the alternator over faster. Any I deas? I looked at the ground to the battery looks fine and the ground going to the alternator housing it to looks fine.
