TROUBLESHOOTING

Inspecting the Fusible Link

If the power is not switched on after turning
the starter switch to the ON position, the
cartridge type fusible links (1) might be blown
open. Open the left side cover and inspect.
If the fusible link is blown, please contact your
dealer.
Supplement: A fusible link is a large piece
of fuse wiring which is mounted in a circuit
which carries a large electrical current. Link
a regular fuse, the fusible link protects the
electrical parts and wiring from damage due
to abnormally large currents.
