Greensmaster 3300/3400Page 6 -- 34Electrical System
Fusible Links
The electrical system on TriFlex Greensmaster ma-
chines include a harness with three (3) fusible links for
machinecircuitprotection.Thisfusiblelinkharnessc on-
nects the machine wire harness to the positive (+) bat-
tery terminal.
Greensmaster 3300 machines (gasoline engine) use
only two (2) oftheharness fusible links. The fusiblelink
harnessonGreensmaster3300machinesisconnected
to the starter solenoid (Fig. 37).
Greensmaster 3400 machines (diesel engine) use all
three(3)oftheharnessfusiblelinks.Thefusiblelinkhar-
ness on Greensmaster 3400 machines is connected to
the starter B+ terminal (Fig. 38). Greensmaster 3400
machines use an additional fusible link that is included
in the wire harness and connects the starter G terminal
to the engine run solenoid pull coil.
If any of these links should fail, current to the protected
circuit will cease. Refer to the electrical schematic and
wire harness drawings in Chapter 10 -- Foldout Draw-
ings for additional circuit information.
Testing
Makesurethatignitionswitchis OFF.Disconnectnega-
tive(--) battery cablefrombatteryterminalandthendis-
connect positive (+) cable from battery (see Battery
Serviceinthe Serviceand Repairs sectionof thischap-
ter). Locate fusible link harness and unplug fusible link
connectorfromwireharness.Usea multimetertomake
surethatcontinuityexistsbetweenthefusiblelinktermi-
nals.If afusiblelinkis open,replacethefusiblelinkhar-
ness.
After testing is complete, make sure that fusible link is
securely attached to engine component and wire har-
ness. Connectpositive battery cable tobattery terminal
first and then connect negative cable to battery.
