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
maxi--fuse is included in the wire harness. This fuse pro-
tects the engine cooling fan circuit and resides in a fuse
holder under the right side cover next to operator seat.

tion switch power supply circuits.
Right Fuse 2 (7.5 Amp): Protects TEC output power
supply for start relay, engine run solenoid, fuel pump,
glow relay, glow plug indicator light and console diag-
nostic light.
Right Fuse 3 (7.5 Amp): Protects TEC output power
supply for fan relay, cutting reels engage solenoid, lift
enable solenoid (S1) and lift/lower solenoid (S2).
Right Fuse 4 (7.5 Amp): Protects TEC output power
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
hour meter, low engine oil pressure indicator light, al-
ternator and proximity switches (parking brake, neu-
tral and mow).
Left Fuse 2 (15 Amp): Protects power supply for
