Diode Assembly - Toro Reelmaster 5010- H Service Manual

Diode Assembly

A diode assembly is used in the Reelmaster main wire
harness (Fig. 62). The diode is used for circuit protection
from voltage spikes that occur when the starter solenoid
is de- energized.
Testing
1. Park the machine on a level surface, engage the
parking brake, lower the cutting units and stop the en-
gine. Remove the key from the ignition switch.
2. Locate diode assembly near alternator on engine
and remove cable tie that secures diode to wire harness.
Unplug the diode from the wire harness for testing.
3. The diode (Fig. 63) can be tested using a digital
multimeter (diode test or ohms setting) and the table be-
low.

4. If testing determines that diode is faulty, replace
diode assembly.
5. After diode testing is complete, make sure that diode
is fully installed into wire harness connector and se-
cured to harness with cable tie.
