It isnt static, everytime you touch it, you get a boot. Its got to do with grounding or/and power box supply not earthing properly. Iv tested what i can without going further. Appliences in van wont work properly either like a/c. im going with the bet it is in supply system. as we hook up to station/rural power, not may eleckys will come out to such remote locations. we have been trying to get hold of one with no luck. typical.
