Well I've checked the grounds, engine to frame/battery to frame/ecu to frame, still hasn't helped. I have an optima yellow top battery, so to eliminate that being the issue I also attacked jumper cables to my Kia run ing. Voltage is a good constant 14.6 attached. So I don't believe it's a charging ground issue.

Letme know what other information about the setup you need. Thank you
