Recently replaced one of two pumps on an older model (1995) Marquis spa (the motor had seized). Before I replaced the pump, the second pump was running just fine. I replaced the pump and now both pumps won’t start. I hear the rely click when I hit the start button but nothing happens at the pump (no hum, no nothing). I have power at both pumps (as indicated by a prox meter (don’t have a multimeter).
I did initially wire the new pump incorrectly (neutral/high wires reversed). Is it possible I messed up the motherboard?
