I have a Morgan Spa with a Gecko circuit board. The 50 amp GFCI breaker tripped a couple of days ago and wouldn't reset. After replacing the breaker and checking the wire, it still would trip.

I started removing the leads from the circuit board for the 2 pumps, blower, heater, ozonator, lights, transformer, etc. until I had nothing connected to the board but the grounding wires and the breaker still tripped. After I pulled off all of the ground wires (i.e, nothing connected to the board) the breaker held and didn't trip.

I got my meter out and started checking some stuff out and got a shock (literally) from the grounding wire disconnected from the circuit board but still connected to the grounding lug on the heater. I checked it with my meter and it was hot. I touched the end to the grounding wire coming from the breaker and it tripped the breaker. After resetting the breaker, I checked some other stuff with my meter and found that the junction box where the circuit board was and both grounding lugs on the heater were hot.

I assume this is a shorted out circuit board. Is this a correct assumption? Is there anything else I need to check before replacing the board? (BTW, where can I get a good quality one at a fair price?)

Thanks for any help you can provide!
