trigger wires hot at switch box

[mustacheyouaquestion]

I was doing some test on the oil pump today so I had it running with the water muffs at idle rpm and noticed that my trigger wires had been hot enough to krinkle the insulation at the switch. It's 99' Bluwater 135 and the has a white, brown and black wires. It has a stacked switch box, one set goes to the top and the other set to the switch box behind..both sets got pretty hot. I've tried to track down all the grounds I could and all were. The motor starts very easy so there is no issue there. Any ideas?
