1 Answer

the MAIN ground connection is violated with corrosion...unbolt that connection and wirebrush the lug by holding it with one hand and wirebrushing it and the chassis from where it bolted....this will restore 300 or more cold cranking amps potential and will service the chassis..fuel pump...ignition...lights and radio too~
