Fuses
The fuse block is located under the control panel (Fig.
26).
Identification and Function
The fuses are held in the fuse block. Use Figure 27 to
identify each individual fuse and its correct amperage.
Each fuse holder has the following function.
Fuse 1 (15 Amp): Protects main power circuit to igni-
tion switch terminal B
Fuse 2 (10 Amp): Protects power circuit from igni-
tion switch terminal S.
Fuse 3 (10 Amp): Protects power circuit from igni-
tion switch terminal I.
Fuse 4 (2 Amp): Protects power supply to Standard
Control Module.
Testing
Remove fuses from the fuse block for testing. Fuse
should have continuity between fuse terminals.

Fusible Link Harness
The Groundsmaster 3280−D and 3320−D use three (3)
fusible links for circuit protection. These fusible links are
located in a harness that connects the starter B+ termi-
nal to the main wire harness (Fig. 28). If any of these
links should fail, current to the protected circuit will
cease. Refer to wire harness drawings in Chapter 11 −
Electrical Diagrams for additional fusible link informa-
tion.
Use a multimeter to make sure that continuity exists be-
tween each terminal pin in connector P1 and connector
J1 at the starter (Fig. 29). If any of the fusible links are
open, replace the complete harness.
