The wire harnesses and electrical components include the
following:
•
Electrical connectors
•
Connector pins
•
Electrical terminals
•
Insulated wire
While you are troubleshooting, inspect the parts for wear
and damage.
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 mispositioned
•
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, repair or replace the wire harness. Contact
your Toro Service Representative for guidance when repairing
wires, terminals, pins, and/or connectors.
If there is damage to the outer insulation only, or if the
damage to the shielding is abrasion or deformation only with
no broken strands, repair the wire harness as follows:
1.
Clean the damaged area of the part with isopropyl
alcohol.
2.
Dry the part with a clean lint-free cloth.
3.
Wrap the damaged area with 2 layers of all-weather
electrical tape or an equivalent.
Note:
Ensure that the tape extends past the damage by a
minimum of 1.3 cm (1/2 inch).
Note:
Heatshrink tape properly installed in the same manner
as electrical tape is acceptable. Install the heatshrink tape
according to the manufacturer’s instructions.
Attaching Wire Harnesses
Properly attaching the wire harnesses to the machine helps
keep the connectors from becoming loose and protects the
harnesses from accidental damage caused by vibration.
•
Ensure that no device used to attach a wire harness to the
machine can rotate or slide freely on the wire harness.
•
For wires not contained in convoluted tubing, secure the
wires with electrical tape or a cable tie every 10 to 15 cm
(4 to 6 inches).
•
For split-loom, convoluted tubing, ensure that the tape or
cable ties are 1.3 cm (1/2 inch) away from any connectors
or labels.
