bad altornater
 

I think my altornater is going bad I was driveing down the road today and stoped to get some gas, and when I went to start the car back up my battery was dead. and on the ride home my volt gauge was realy low and the car was running like shit just berly pulling it self along I just berly made it up the hill to my house,and when I pulled in to my house my car was idleing lower than it usually dose and when I shut it off the battery was dead again.

Try this: Start car disconnect the + battery cable while it's running if it cuts off, go buy a new alternator. Have fun!

Ill give it a shot tomarow.I started it up after I charged the battery it starts and idles like normale but im sure if I took it down the road and put some load on it again it would start sputering again! the volt gauge reads exactly 12volts when its running and isnt it supost to be like 14 volts when its running?It was at like 10 volts on the drive home from the gas station when it was lugging it self along if the altornater is bad would putting more load on the engine make the volts drop? couse that would explain why they were as low as 10 volts when I was trying to clim that hill.

ok I took the positive battery cable off wile the car was running it stalled. but I took it to advanced auto to have it tested they said it was fine but I dont trust them its only puting out 12.75 volts wile its running Im definetly going to get a new altornater.but would the failing altornater be the resone my car could berly pull it self.
