After A/C Add On Engine Overheats Really Bad

Not sure about the a/c issue but the starting after its hot I may know why. My Dart would refuse to start when it got hot. I talked to an old timer and he told me to put the fattest ground cable I could find on the battery. I thought he was crazy and continued jacking with everything I thought was wrong. After a day screwing with it I figured I would try his idea and I chit you not worked perfectly. I couldn't believe it.
