Diagnostic Aids

Any electrical condition that interrupts normal operation of pump/motor relay or pump/motor power circuits can cause an inoperative pump/motor, including a short to ground on circuit No. 864. A failed pressure switch that is not providing a path to ground will also cause an inoperative pump/motor.
