A couple weeks ago my Sunbelt Spas hot tub stopped working. I tracked it back to a tripped GFCI breaker. I reset the breaker and turned on the power again and the breaker tripped instantly. I disconnected the heater, pumps, blower, and ozone but it still kept tripping the breaker. Finally, I removed the power and determined that there was a short between the white neutral terminal and the black hot terminal on the board. Figuring something had happened, I ordered a replacement board. The board just arrived, but it too seems to have a short between the neutral and black hot terminals. There is no short between the neutral and red hot terminals nor between both black and red hot terminals. I'm hesitant to install it like this. Is this normal, or is the new board bad as well? I have checked my wiring and there does not appear to be any problems there. With the power off there are no shorts between either hot and the neutral and ground wires. With the power on I measure 240V across the two hots, and 120 between each hot and the neutral. Is there anything else I should check? Should I return the board for a replacement? Thank you. Kevin
