autozone sucks donkey balls.

 

The 3 times I have taken batteries, or alternators down there they have been completly wrong on the status of the part I have brought them.

 

Hook up your multimeter and see what voltage you are getting, with the car running you should be getting around 14.1v.

Disconnect battery, if the car stays running, its good.

 

 

Pleas tell disconnect neg or positive cable? Will this damage the engine? Thanks for reply!

Please tell what if it low than 14.1V or higher than 14.1 V? Thanks for reply.
