Toro 30446 - Fuses

Groundsmaster 4000--D/4010--D Page 5 -- 21 Electrical System
Fuses
The fuse blocks are located in the power center under
the hood on the right side of the machine (Fig. 17).
Inadditiontothefuses inthe fuseblocks, a40 ampfuse
(F5--1) is includedin the wire harness toprotectthepull
coilcircuit fortheengine run solenoid.This fuse resides
in a fuse holder near the starter motor (Fig. 17).
Fuse Identification and Function
UseFigure18toidentifyeachindividualfuseanditscor-
rectamperage in the fuseblock.The fuses havethefol-
lowing functions.
FuseF1--1(20amp)protects engine starter circuit.
Fuse F1--3 (10 amp) protects light circuit on Ground-
smaster 4010--D.
FuseF1--4(10amp)protects signal light circuit on
Groundsmaster 4010--D.
FuseF2--2(10amp)protects operator seat circuit.
FuseF2--3(10amp)protects power point circuit.
FuseF2--4(10amp)protectsmainpowersupplycircuit.
Fuse F3--1 (2 amp) protects logic power circuit to the
TEC--5002 controller.
Fuse F3--2 (7.5 amp) protects power supply for the
TEC--5002 controller outputs.
Fuse F3--3 (7.5 amp) protects power supply for the
TEC--5002 controller outputs.
Fuse F3--4 (7.5 amp) protects power supply for the
TEC--5002 controller outputs.
Fuse F4--1 (2 amp) protects logic power circuit to the
TEC--5001 controller.
Fuse F4--2 (7.5 amp) protects power supply for the
TEC--5001 controller outputs.
Fuse F4--3 (7.5 amp) protects power supply for the
TEC--5001 controller outputs.
Fuse F4--4 (7.5 amp) protects power supply for the
TEC--5001 controller outputs.
FuseM1(60A)protects engine glow plug circuit.
FuseM2(60A)protectsoperatorcabcircuitonGround-
smaster 4010--D.
Fuse Testing
Turn ignition switch to the ON position (do not start en-
gine). With the fuse installed in the fuse block, use a
multimetertoverifythat12VDCexistsatboth oftheter-
minal test points on the fuse. If 12 VDC exists at one of
thefusetestpointsbutnotattheother,thefuseisfaulty.
If necessary, make sure that ignition switch is OFF and
key is removed from switch. Remove fuse from fuse
blockandcheckthatfusehascontinuityacrossthefuse
terminals.
