Diode Assembly; Fusible Link Harness - Toro Reelmaster 5210 Service Manual

Diode Assembly

A diode assembly (Fig. 45) is used in the Reelmaster en-
gine wire harness (see wire harness drawings in Chap-
ter 9 -- Electrical Diagrams). The diode is used for circuit
protection from voltage spikes that occur when the start-
er solenoid is de--energized.
Testing
Locate diode assembly and remove cable tie that se-
cures diode to wire harness. Unplug the diode from the
wire harness for testing. The diode (Fig. 46) can be
tested using a digital multimeter (diode test or ohms set-
ting) and the table below. After testing is complete,
make sure that diode is fully installed into harness con-
nector and secured to harness with cable tie.

Fusible Link Harness

The Reelmaster uses three (3) fusible links for circuit
protection. These fusible links are located in a harness
that connects the starter B+ terminal to the main wire
harness (Fig. 47). If any of these links should fail, current
to the protected circuit will cease. Refer to wire harness
drawings in Chapter 9 -- Electrical Diagrams for addi-
tional fusible link information.
Testing
Make sure that ignition switch is OFF and disconnect
negative battery cable from battery terminal. Then dis-
connect positive cable from battery (see Battery Service
in the Service and Repairs section of this chapter). Lo-
cate and unplug fusible link connector P1 from machine
wire harness. Use a multimeter to make sure that conti-
nuity exists between each terminal pin in connector P1
and connector J1 at the starter (Fig. 48). If any of the fus-
ible links are open, replace the fusible link harness.
After testing is complete, make sure that fusible link har-
ness connectors are securely attached to starter and
machine wire harness. Connect positive battery cable to
battery terminal first and then connect negative cable to
battery.
