airjordan223 Posted November 12, 2010 Share Posted November 12, 2010 Take it to autozone and they do a test for free Quote Link to comment Share on other sites More sharing options...
cmgogo Posted November 12, 2010 Share Posted November 12, 2010 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. Quote Link to comment Share on other sites More sharing options...
