A1MC : Low Current Motor

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

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


  • Fluid is in the pumps.
  • Inlet valves are open.

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


  • 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

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 (2 to 3, 3 to 4, 2 to 4). If any readings greater than 8 ohms and previous step ("Loose/broken power connection or motor cable") were verified, then motor may need replacement.
