1. 75 ohm resistor
A 75 ohm resistor assembly is used for proper key switch (start circuit) operation.
The resistor plugs into the main wire harness above the right rear corner of the
operator's platform. The resistor can be identified by its gray color and resistor
symbol on the end of the resistor body.
1. Park the machine on a level surface, lower the cutting unit (or attachment),
engage the parking brake, set the key switch to the O
the key from the key switch.
2. Disconnect the resistor from the wire harness. Check the resistor and the
resistor holder for damage or corrosion and clean or repair if necessary.
3. Measure the resistance across the resistor terminals using a digital
multimeter (ohms setting). The resistance across the terminals should be at
or near the resistors rated resistance.
4. If testing determines the resistor is faulty, replace the resistor.
5. If the resistor tests correctly and a circuit problem still exists, check the wire
harnesses; refer to
6. After testing is complete, make sure the resistor is fully installed into the
connector and secured to the wire harness.
