mechanically identical and will interchange, the switch knobs being
differently marked. If one switch is suspect, take off the lamp rim and
glass. Pull off the cable plugs and reverse their location. A further check
will indicate if the switch is defective or otherwise. Replace the cable
plugs in correct position after changing the switch.
Replacement switches should be of the improved type which can be
identified by a NYLON post for the switch knob. Old type switches use
a steel post.
Plug location. The blue plug is for the lighting system and the black for
ignition.
Lamp bulb 'blowing'. Premature bulb failure involving all or many of
the light bulbs at one time on a full d.c. battery system is caused by a
defective connection in the battery 'line'.
This 'line' starts at the frame end of the translucent lead from the
positive battery terminal and proceeds:
(2) Positive battery terminal.
(3) Negative battery terminal.
(4) Brown wire from battery negative to 4-hole connector (bullet ter-
minal).
(5) Brown wire from 4-hole connector to ammeter (bullet terminal).
(6) Ammeter terminal with brown wire.
(7) Ammeter terminal with blue wire.
(8) Both ends of short insulated link wire in the ignition switch plug,
which joins blue ammeter wire to brown wire going to lights switch.
Should the ammeter develop internal open circuit, bulbs will blow, also
should the battery have little or no electrolyte, this is a partial or com-
plete open circuit with the same results. There is finally the remote pos-
sibility af one of the actual wires in the battery 'line' being broken—again,
bulbs will 'blow'.
For quick checking, test connections in this order:
(1) Both battery terminals.
(2) Both ammeter terminals.
(3) All brown wires into 4-hole connector.
Speedometer bulb . On models made before 1961, the speedometer bulb
is in circuit during daylight running and fails from filament fatigue. Trans-
fer the wire attached to the speedometer bulb holder and connect it to
the light switch as shown in wiring diagram for 1962 models, to illumi-
nate the speedometer when lights are in use.
Ignition system.
SPECIAL NOTE— The star-shaped washer for contact breaker pivot is
not detachable. If the engine fails to start and there is no spark at the
sparking plug points, examine the contact breaker by:
Check the gap at full separation .012" and reset if necessary (ensure
feeler gauge is free from oil),
Check conditions of contact points which should have a grey frosted
condition. The presence of oil or grease in the contact breaker compart-
ment will cause a black matt condition.
