TROUBLESHOOTING AND ELECTRICAL
SYSTEM: DIESEL VEHICLES
TEST PROCEDURE 7 – Starter Control Circuit
See General Warnings, Section 1, Page 1-2.
1. Disable the vehicle. See Disabling the Vehicle on page 1-3.
2. Disconnect the 16-gauge green wire (w127) from the starter solenoid coil to prevent the vehicle from
unintentionally starting
(Figure 12-10, Page 12-18) . See following WARNING.
WARNING
• Failure to disconnect the wire from the solenoid coil could result in an unexpected engine start
when performing this test.
3. Set the multimeter to 20 VDC.
4. Place the probes to measure the voltage between the 16-gauge green wire (w127) terminal and the frame
ground
(Figure 12-11, Page 12-18) .
5. Monitor the multimeter. The reading should indicate 0 volts with the key in the OFF and ON positions. The
reading should indicate approximately 12 VDC when the key is in the START position.

6. If the readings differ from those described in step 5, perform the following test procedures:
– Check the battery.
See Test Procedure 1 – Battery on page 12-10.
– Check the 30-amp fuse on w109 at the fuse block. See Test Procedure 2 – Fuse on page 12-13.
– Check the start relay. See Test Procedure 8 – Start Relay on page 12-19.
– Check diode 6. See Test Procedure 15 – Diode 3 on wire 123 on page 12-27.
– Check the neutral switch on the transmission housing. See Test Procedure 17 – Neutral Switch
(Transmission) on page 12-30.
– Check for continuity of the wire harness on wires 127, 128, 147, and 109. See Wiring Diagram on page 12-7.
7. If none of the previous steps resolves the problem, the starter solenoid and/or starter motor has failed. See the
Kubota D722 diesel engine manual (CC P/N 103840201).
