5 Electrical Troubleshooting
Solenoid / Starter Tests

4. Probe the mounting base of the solenoid. Probe
small post #1 and observe the VOM. Probe post #2
and observe the VOM. The VOM should read no
continuity in both cases.
5. Apply 12 VDC to the two small posts. There should
be an audible click as the solenoid engages.
6. With the solenoid engaged (12 VDC to the small
posts), measure the resistance at the two large posts.
The VOM should read less than 10 ohms (continuity).
7. Correctly reinstall the solenoid and all related wires
and connectors.
G. Test Power to Starter
For this, and all tests, the ground speed control lever
must be in the neutral gate, the parking brake set, and
the PTO switch must be OFF. Unplug and secure all
spark plug wires.
1. Set VOM to VDC.
1. Probe ground. Pull the boot back and probe the
starter post (see Figure 22).
2. Turn the ignition switch to start.
The VOM should read battery voltage.
