Fusible Link Harness
The Groundsmaster 7200 and 7210 uses three (3) fus-
ible links for circuit protection. These fusible links are lo-
cated in a harness that connects the starter B+ terminal
to the main wire harness. If any of these links should fail,
current to the protected circuit will cease. Refer to Elec-
trical Schematics in Chapter 8 – Foldout Diagrams for
additional circuit information.

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. 23). 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.
Diode Assembly
The diode assembly is used for circuit protection from in-
ductive voltage spikes when the PTO clutch is de–ener-
gized. The diode plugs into the wiring harness under the
operator seat.
