Have m998 that has no power out of nowhere. I get many on this site are great at taking these trucks apart and getting them repaired. Many have already sent suggestions. Batteries seem to test out fine, but I got two new ones to drop in and try. I am still learning. With this said, I am looking for someone in SE Michigan area that works on these for a fee. At this point, I would rather pay someone to get it working again. It is in driveway, freezing outside, busy as **** with work, and I just want to drive it again. I hope you can respect this. There is a shop I work with for other "normal" vehicles, but these are unique and not sure if makes sense to have them look at. Anyone out there have suggestions for now and in future?
