Testing the Nozzle Motor
1. Make sure that key switch is in the O
FF
position.
2. Disconnect the nozzle motor connector from the wire harness.
3. Connect a 12 VDC power source (machine battery) to the nozzle motor
terminals. The motor shaft should rotate clockwise (viewed from the shaft
end) smoothly and quietly when the positive (+) lead of the power supply
is connected to the (C) terminal of the motor connector, and the negative
(-) lead of the power supply is connected to the (B) terminal of the motor
connector. The motor shaft should rotate smoothly and quietly in the opposite
direction when the power supply wires are reversed.
4. Loosen the nozzle motor bracket and remove the drive belt from the motor
pulley.
5. Connect an ammeter or multimeter (DC amps) into the positive (+) lead of
the power supply. The motor should draw less than 2 amps under no load.
6. Replace the motor assembly if necessary; refer to Nozzle Motor (page 5–32) .
7. If the nozzle motor tests correctly and a circuit problem still exists, check the
wire harness; refer to Appendix A (page A–1) .
8. Install the nozzle motor assembly and drive belt if necessary and connect
the wire harness after testing.
