A 75 ohm resistor assembly is used for proper key switch operation. The
resistor plugs into the console wire harness near the key switch (see
A (page A–1)). The resistor can be identified by its gray color, resistor symbol
and Toro part number on the end of the resistor body
•
A 1.6K ohm (1600 ohm) resistor assembly is used for proper 12 Volt
alternator operation. The resistor plugs into the engine wire harness near the
starter (see Appendix A (page
gray color, resistor symbol and Toro part number on the end of the resistor
body (Figure 257).
•
A 2K ohm (2000 ohm) mini resistor is used for monitoring the 24 Volt
electrical system. The resistor plugs into diode block 2 in the front power
center behind the operator seat
by its silver color and resistor symbol on the end of the resistor body
259).
1. Disconnect the resistor from the wire harness or remove the diode block
cover and pull the resistor from the diode block.
2. 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. Replace the resistor if a reading other
than the rated resistance is obtained.
A–1)). The resistor can be identified by its
