Hi, I really want to convert my bullfrog that was converted to 120v at the factory back to 240v. I understand to unplug the jumper wire between j35 and j64 and where the 240v wires go, but right now the only dip switch that is "on" is #4. I don't know how to set the dip switches back for 240v? Anyone that can help me would be awesome! Thank you
