Pass The key switch tested good. Go to
the steps listed.
Fail The key switch failed the test. Replace the key switch. Go to
(page 19) and follow the steps listed.
Step 4: Remove 2 access covers to aid troubleshooting.
Performing these steps provides access to connectors on the wire harnesses.
1. Remove the console cover. Refer to
2. Remove the power center cover. Refer to
Step 5: Use a multimeter to check battery voltage, the battery wire harness for
continuity, and verify that there are no short conditions.
Note: You will find additional wire harness and connector information in
Appendix B: Toro Electronic Controller Connections (page
Note: Inspect the wire harnesses for damage and wear while checking the items in the following steps. Refer to
Wire Harnesses and Component Connector Assemblies (page
Step 5.1: Check for battery voltage and possible damage to the battery wire
harness and to the main wire harness.
Use the Li+ diagnostic wire harness, Toro P/N 120-6339.
Step 5.1.1: Check the operation of the machine.
1. Install the Li+ battery diagnostic wire harness. Refer to
2. Start the machine.
Note: If the machine starts, the fault is likely in the battery wire harness.

2. Disconnect the battery pack by disconnecting the Li+ diagnostic wire harness P04 connector. Refer to
Disconnecting the Battery Pack (page
3. Attach the multimeter to the Li+ diagnostic wire harness P04 connector, POS and NEG pins.
Note: After you connect the P06 and P07 connectors together in step 4A, the voltage will only be present
for approximately 2 to 3 seconds to accomplish Step 4B.
4. Perform the following 2 steps (A and B) simultaneously:
A. On the diagnostic wire harness, connect the P06 and P07 connectors together. Refer to
B. As you connect the P06 and P07 connectors together, read the voltage on the multimeter. The
