Good evening all, it appears to be a widely covered topic across the forum but this appears to be the best established thread. I had initially had this issue and fixed according to this thread and all my problems were solved for months. Now it’s happening again...I’ve gone in and re did the ground and the issue still persisted. Went back in and sanded and cleaned and are still having the issue. very frustrating and want to get this fixed before I end up in an accident. If the G218 isn’t the culprit anyone have experience in where to go next? Would it be dumb to run a wire from my negative terminal of battery to g218 ground post? Not sure if I would gain anything but something I thought of as my truck died again pulling into drive way... thank you in advance for any help
