Trim Pump Motor Test
WARNING
Do not perform this test near flammable materials,
as a spark may occur while making electrical
connections.
1. Connect a 12 volt power supply to motor wires
[positive (+) to blue wire and negative (-) to black
wire]. Motor should run. Disconnect blue wire and
connect green wire to positive (+) terminal of pow-
er supply. Motor should run.
2. If motor does not run, disassemble and check
components.
Solenoid Test
WARNING
Do not perform this test near flammable materials,
as a spark may occur while making electrical
connections.
1. Disconnect all wires from solenoid terminals.
2. Set an Ohmmeter to Rx1 scale and connect meter
leads to solenoid terminals 1 and 2.
3. Connect a 12 volt power supply to terminals 3 and
4. Solenoid should click and meter should read
zero (0) ohms (full continuity).
