I have a 1998 42 Putz. that keeps going from snail to Rabbit on the boom functions. We are running the rectangular HBC 3 stick remote box. We have replaced the snail remote switch with no change. I understand that the switch cuts the voltage in half and then only partially moves the dump valve on the boom circuit.My question is what does the remote talk to in the boom circuit to cut the power? Is it a relay in the control box? Or could it be in the receiver or radio itself?
