Having a problem with my calspa. Came out this morning and it was offline, breaker would instantly pop. Narrowed it down to the connections from the board to the heater. Using port SH7 on the circuit board, I could connect to either heater port and it doesn't trip. If I connect either to the SH6 port on the circuit board, it trips instantly. So if I'm reading this correctly, the heater is fine but there is some problem with that port on the circuit board? Is there anything I can do to further troubleshoot this or is this a "need new board" situation?
