HI all, I think I might have found the reason the Power box opened two matched channels when the turbine was running, bad install.
I can not think of any other reason the PB failed, but from static electricity from a bad install, the pump and fuel lines too close to the receiver and Power box, see pic and see if you guys agree.
First runs in Florida where hot and humid, in Canada last week, cold and dry.
