How old is the battery? seven years old means it is time to replace that one...also the battery connections must be solid and free of any corrosion . clean them with a wirebrush and the 1/0 cable leading to the engine too- -examine the positive terminal and be sure the little lolipop connection return from the alternator is clean too-

I believe it is a matter of bad ground and possibly weak battery too-
