SPARK PLUGS
IMPORTANT: Always carry spare fuses. Use the
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.

they are badly fouled.

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.

Fuse Failure
A minor electrical problem can blow a fuse. Re-
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.
