Inspecting The Wire Harnesses And Component Connector Assemblies; Repairing Harness Wire Insulation - Toro Greensmaster e1021 Diagnostic Manual

M/S Samsung Service Wire Harness
Toro P/N 122-1947
Use the M/S Samsung service wire harness when troubleshooting to:
•
determine if the BMS controller is working correctly
•
determine if the M/S Samsung interface wire harness is working correctly
Note:
While a battery-related fault is active, the BMS controller keeps its internal battery contactor open, not
allowing battery power to go to the machine. As a result, the machine will not respond when the key switch is
turned to the O position.

Inspecting the Wire Harnesses and Component
Connector Assemblies
The wire harnesses and electrical components include:
•
Electrical connectors
•
Connector pins
•
Electrical terminals
•
Insulated wire
While you are troubleshooting, inspect the parts for wear, damage, and corrosion.
Common electrical problems include:
•
Open, shorted, or burned wires
Note:
Debris, such as wet grass clippings, can act as a conductor.
•
Corroded terminals or pins
•
Water in the connector
•
Connector pins that are loose, bent, or recessed
•
Connectors that are not fully seated
•
Wires that are pinched, frayed, or are missing insulation
•
Damaged connector locks, clips, or housings
•
Missing or inadequate dielectric grease
Note:
Dielectric grease is used in all unsealed wire harness connectors.

Repairing Harness Wire Insulation

If damage extends through the insulation and strands of the wire are broken, replace the wire harness.
