1. Engine
On machines with a Yanmar diesel engine or Kubota gasoline engine, a 75
ohm resistor (Figure 280) is necessary for proper key switch operation on all
Reelmaster machines. The resistor plugs into the engine wire harness near the
engine ECU; refer to the Engine Wire Harness Drawing/Diagram in
(page A–1).

1. End of the resistor body
The resistor assembly can be identified by its gray color and resistor symbol on
the end of the resistor assembly body
1. Park the machine on a level surface, set the parking brake, lower the cutting
units, and shut off the engine, and remove the key from the key switch.
2. Locate the resistor assembly in the engine wire harness and remove the
cable tie that secures the resistor to the wire harness. Unplug the resistor
from the wire harness for testing.
3. Use a digital multimeter (ohms setting) to measure the resistance value for
the resistor. The resistance across the resistor terminals should be 75 ohms.
