If you think your having ground problems, try this first. Find the ground from the chassis battery. Follow the end from the battery to where it connects to either the frame or engine. Remove and clean thoughly including battery end. Next find the negative end from the house battery, clean both ends and reattach. Now check to see if your having problems. Good luck.
