I've installed the kill switch (+&- correctly on the coil and the way they came off the switch too). The other day while driving maybe 5 minutes, the truck ran away on me! Batteries in controller new, and fully charged hump in truck! I've got it on channel 3 on my receiver... Thinking hard about using this as when I don't use it, truck runs fine! Any ideas as to what is causing this? In assuming a short it something... But I'll be damned if I can find anything lending to that!
