Pump M−
Condition
External short of pump
motor M− to B−.
Truck Response
No Lifting
Possible Causes and Test
Procedures
1. Incorrect pump motor
wiring.
Check wiring to pump
motor.
Ensure all wiring
connections are tight.
2. Pump motor shorted to
frame.
Disconnect motor leads
at motor or controller.
Measure resistance
between motor terminals
and truck frame. If less
than 1 megohm, replace
motor.
3. Check for shorted
controller.
Disconnect pump motor
leads at controller.
Measure resistance
between B− and Pump
M− at the controller. If
less than 1 megohm,
replace controller.
Circuit Description
Logic
The controller uses an internal check to ensure the pump motor M− connection is not
shorted to B− (Battery Negative).
