Q: Battery sparking

asked by on

I just changed alternator and now batter is sparking

My car has 150 miles.
My car has a manual transmission.

Hi There, This may sound a bit like stating the obvious, but this happens all too frequently even with some very technically able mechanics; check to be sure the positive cable is connected to the positive terminal and negative to negative terminal. If this is not the problem, you may also want to check for shorts by using an ohm meter checking shorts to ground. This is also a very common problem when battery cables spark as you describe. You may want to have a professional from YourMechanic come to your location to diagnose and inspect your vehicle for this.
