The voltage regulator circuit and the electric starting circuit are protected from

overload by 20‑amp and 15‑amp ATC fuses, respectively. If a fuse opens, try to

locate and correct the cause of the overload. If the cause is not found, the fuse

may open again.

c -

15‑amp fuse—Electric starting circuit

d -

Spare 15‑amp fuse

To access the 15‑amp fuse, remove the fuse block from the pocket on the ECM

rubber mount. Then remove the cap from the fuse block.
Remove the fuse and examine the silver colored band inside the fuse. If band

is broken, replace the fuse. Replace the fuse with a new fuse of the same

rating.
