spare fuse holder to hold an extra fuse.
WARNING
The fuse is located in the fuse holder. Refer to En-
gine Specifications.
The   ignition  system   presents   a   serious
shock hazard. The primary circuit operates
in excess of 250 volts; the secondary circuit
operates in excess of 25,000 volts. Use cau-
tion  to  avoid  injury  from  shock  or  injury
resulting  from  your  reaction  to  shock.  Do
not  handle  primary  or  secondary  ignition
components while the engine is cranking or
running.

Fuse holder
To install spark plugs, wipe spark plug seats clean
with a clean rag. Install spark plugs finger tight, then
tighten to specified torque. Refer to Engine Speci-
fications.
IMPORTANT: Avoid engine damage by installing
spark plugs into COOL cylinder head and not over-
tightening.
Before installing the spark  plug lead, apply a light
coat of Triple-Guard grease to the ribbed portion of
the spark plug. This will help prevent corrosion be-
tween the spring terminal and the spark plug.

place it with a fuse of the same rating.
Repeated failures of fuses in the same position in-
dicate  a  serious  problem.  Do  not  replace  it  with
higher rated fuses; see your Dealer for service.
