Fuse Block (Greensmaster 3400 with Serial Number Below 312000000)
The fuse block on Greensmaster 3400 machines is at-
tached to the frame under the operator seat (Fig. 33).
In addition to the fuses in the fuse block, a 50 amp

UseFigure34toidentifyeachindividualfuseanditscor-
rect amperage. Fuses for Greensmaster 3400 ma-
chines Greensmaster 3400 machines with a serial
number below 312000000 have the following function:
Right Fuse 1 ( 2 Amp): Protects TEC logic and igni-
tion switch power supply circuits.
RightFuse2(7.5Amp):ProtectsTECoutputpower
supplyforstartrelay,enginerunsolenoid,fuelpump,
glowrelay,glowplugindicatorlightandconsolediag-
nostic light.
RightFuse3(7.5Amp):ProtectsTECoutputpower
supplyforfanrelay,cuttingreelsengagesolenoid,lift
enable solenoid (S1) and lift/lower solenoid (S2).
RightFuse4(7.5Amp):ProtectsTECoutputpower
supply for lift solenoids S3 (front cutting units), S4
(center cutting unit) and over temperature indicator
light.
Left Fuse 1 (10 Amp): Protects power supply for
hourmeter,lowengineoilpressureindicatorlight,al-
ternatorandproximity switches(parking brake,neu-
tral and mow).
Left Fuse 2 (15 Amp): Protects power supply for
start relay and solenoid.
LeftFuse3(15Amp):Protectspowersupplyforop-
tional Turf Defender

Leak Detector system and
optional lights.
Left Fuse 4: Not used.
Fuse Testing
Make sure that ignition switch is OFF and key is re-
moved from switch. Remove fuses from the fuse block
