Well I disconnected all relays from the board and the breaker still trips. I also dosconnected the pump load from its relay and still the breaker trips.You are now stuck with the problem of diagnosing which device is causing the breaker trip when many devices are fed by one breaker.
You need to use a process of elimination and disconnect everything you can and then connect then back one at a time.
I would begin with pulling the plugs from all the relay connections to the PCB. Label everything before you disconnect so you know where to reconnect.
If the breaker trips then you will need to start disconnect wires in the Aqualink.
If the breaker does not trip then connect one relay at a time and see which one trips the breaker.
So the breaker doesn’t trip after I disconnected the jumper from the back left relay power line to the front left relay line which powers the aqualink and the blower with the heater connected to the line side for some reason. That heater connection seems strange to me. Why isn’t the heater connected to the load side of that relay?
Does this mean something has gone bad on the aqualink?
