Resistor Test
See Figure 4-34.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Remove resistor.
Figure 4-34
3. Using a multimeter or ohmmeter, measure the
resistance between terminals (1 and 2).
Is the resistance value approximately 2500
ohms?
YES The resistor is good.
NO The resistor is faulty; replace the resistor.
Diode Test
See Figure 4-35.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Remove diode.
Figure 4-35
3. Using a multimeter or ohmmeter, check for continuity
between terminals (1 and 2). Reverse the lead wires
and check for continuity again.
Is continuity indicated in one direction and not in
the other direction?
YES The diode is good.
NO The diode is faulty; replace the diode.
