IGNITION
COIL
To
test primary and secondary windings within the
ignition coil proceed as follows:
Use a Simpson
260
VOM or equivalent
Place black lead on ground (-)terminal of coil and
red lead to positive (+)terminal. Primary resistance
should read 3.87
-
4.73
ohms.
Change resistance setting on ohmmeter. Place
ohmmeter leads inside of spark plug cable holes
(Figure
3).
Secondary resistanceshould read 12,600
-
15,400 ohms.
If any of the above conditions are not met, replace
coil. Refer to
PARTS CATALOG
for correct part
number.

PLUGS
Check, and regap spark plugs as recommended in the
Periodic
Maintenance
Schedule
(located in Operator's
Manual). Replace spark plugs that show signs of fouling
or electrode erosion.
BATTERY INSPECTION
Check battery cells with a hydrometer. The specific
gravity reading should be approximately 1.260 at 77OF
(25"C), Figure
5.
If one or more cells are low on water, add distilled water
and recharge. Keep the battery case clean and dry. An
accumulation
of
moisture will lead to a more rapid
discharge and battery failure.
Keep the battery terminals clean and tight. Push the
cable terminal down flush with or slightly below the top
of the battery post (Figure 6).After making connections,
coat the terminals with a light application of petroleum
jelly or grease to retard corrosion.
Poor contact at the battery cable connections
is
often a
source of trouble. Make sure battery cables are in good
condition and that contacting surfaces are clean and
tightly connected.
Do
not reverse battery leads. Use
recommended battery tools when disconnecting leads
to avoid mechanical battery damage.
/Snition
of
explosive battery gases
can
result
in
severe personal injury.
Do
not
smoke
or allow any ignition
source
near the
battery.
