Pass
Continuous 42 to 64 Vdc tested good at the listed locations. Go to
to Service (page 19)
and follow the steps listed.
Fail
A voltage difference was found. This may indicate a pre-charge circuit failure. Go to step 5.
Step 5:
Use a multimeter to check the wire harness for continuity, and measure
coil resistance.
Note:
You will find additional wire harness and connector information in
Appendix A: Wire Harnesses (page 113)
and
Appendix B: Toro Electronic Controller Connections (page 135)
.
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 13)
.
Disconnect the battery pack. Refer to
Disconnecting the Battery Pack (page 17)
.
Note:
Troubleshoot 1 circuit or component at a time. Disconnect or isolate each component or wire harness section from
the system before testing.
