Is your ground wire same gage as power causing a poor ground ? Are you grounded to frame or body ? If body , is the body to battery ground same gage as the power in ? Have you tried putting a fan in to circulate cool air? I get mine from computer supply shop. First fan I used , I just stripped it out of a computer power supply box I picked up for $5.00 at local pawn shop. Just my thoughts.
