V. ELECTRICAL EQUIPMENT

1. Alternator

Electric current is supplied by the alternator
fitted with a rotor with permanent magnets. The
lamps are fed with current from three stator coils
Lamps:
Headlight
Tail light
Speedometer lighting
(outside bulb fastening)
Speedometer lighting
(inside bulb fastening)
2. Ignition
Contactless, thyristorized system with plastic
encapsulated semiconductor device. The ignition
coil is enclosed in a cylindrical aluminium case.
Feeding
Starting
Spark plug
Plug point gap
Ignition advance
The described ignition system of the moped does
not require any maintenance apart from occasional
cleaning of the spark plug. Any defect which might
occur is usually the result of unskilled interference
or rough handling on the part of the user. Adjust-
ment of the ignition advance is likewise not ne-
cessary as there are no parts subject to wear. The
only instances in which the advance has to be re-
adjusted is the working loose of the stator screws
or the removal of the alternator. Therefore refrain
from interfering with the ignition system in any
way. In the case of a defect, have the repair done
by a skilled electrician.

— 1-1.5 mm before T.D.
connected in series with an output of 20 W at a
voltage of 6 V.
Another stator coil supplies current to the ignition
coil and the thyristor block controlled by the
pulse-forming stator coil.

To adjust the ignition advance, turn the rotor
in the direction of the arrow ,,A" (Fig. 29) till the
index lines (timing marks) ,,B" on the rotor and
stator coincide. Insert an indicator or a depth slide
gauge into the spark plug hole and measure
the depth to the retracted piston. Then continue
rotating the rotor in the direction of the arrow
,,A" till the piston reaches its top position (T.D.C.).
The distance read off the indicator or depth
gauge from the point of the coincidence of the
timing marks to the piston T.D.C. should be 1
to 1.5 mm. If this distance is greater, loosen the
screws (E) — Fig. 30, and turn the stator in the
direction indicated by the arrow ,,C". If the dis-
tance is smaller, turn the stator in the direction
of the arrow ,,D".
Repeat this procedure till obtaining the specified
advance of 1 to 1.5 mm. Then retighten the
screws ,,E" and recheck the advance.
