Troubleshooting Procedure for Brush Type Motors
1. Remove the pump pin and try to run the sprayer. If the motor runs check
for locked or frozen pump or drive train. If sprayer does not run, go to
next step.
2. Set sprayer to OFF and
disconnect power to sprayer
.
3. Disconnect motor connector(s) from control board socket(s). Check that
motor connector and control board contacts are clean and secure. If ok go
to Step 4.
4.
Check motor. See Motor Testing .
Or connect a D.C. voltmeter across
two motor wires – red & black spin the motor fan and check for a voltage
to register on the meter. If voltage
not
present, check brushes. If ok,
replace motor. If voltage present, go to next step.
5. Reconnect motor connector(s) to control board socket(s). Connect
power,
set sprayer ON and control knob to ½ turn clockwise. If motor does not
run, replace control board
