A1NM : Low Motor Current

To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.

Fluid is not in system

No fluid in the pump can cause a low motor current error. Verify:

Fluid is in the pumps

Inlet valves are open

System cannot build pressure

An outlet restriction does not exist. Verify relief valves are in SPRAY position.

Loose/broken connection

Verify:

Power connector is tightly connected at MCM port #15. Confirm wiring is not pulling connector out of proper position

Cable insulation or wire is not cut or frayed.

Wires are tightly torqued in power connector terminals. Test by pulling on individual wires in power connector.

Cable not damaged at strain relief on motor case

Bad Motor

Disconnect motor power connector at MCM port #15. Measure resistances at motor power connector.

Must read less than 8 ohms resistance between each pair of motor power leads (M1 to M2, M1 to M3, M2 to M3). If any readings greater than 8 ohms and previous step ("Loose/broken power connection or motor cable") was verified, then motor may need replacement.
