good. now you need to tend to that MAIN ground connection at the end of that battery clamping 1/0awg cable as it attaches to the chassis ground~ wirebrush the lug and the frame to assure solid 300 or more cold cranking amps~ the little blue spark of dis-similar metals creates a layer of semi- conductor over the years and needs to be cleaned off~
