If the external wiring is ok (no short circuits) the motor is shorted internally, Use a VOM to check the voltage level at the pressure control switch, If voltage is too low, check voltage at the electrical panel and check that the proper size wiring was used for the ampacity and length of run and that there are no partial shorts or damaged wires or connectors, Check the actual electrical wiring against the motor wiring diagram or the installation manual for the equipment, Motor is too hot due to surroundings - inadequate ventilation, Install adequate ventilation, or if needed, shading, or relocate the motor/equipment to a cool location, Pump operates too long at low water pressure. Do you think the two are related. etc. Step 4 Visually inspect the control panel's wires, wire connections, relay and capacitor. Leave the circuit off to avoid a fire and shock hazard - sorry I know that's not exactly convenient. or Best Offer. Often the cause is a water-logged pressure tank.
