A 75 ohm resistor (Figure
on all Groundsmaster 4300-D machines. The resistor plugs into the engine
wire harness near the engine ECU; refer to the Engine Wire Harness
Drawing/Diagram in Appendix A—Foldout Drawings.
The resistor assembly can be identified by its gray color and resistor symbol on
the end of the resistor assembly body.
The resistor can be tested using a digital multimeter (ohms setting).
Note: The resistance across the resistor terminals should be 75 ohms.
