ELECTRICAL SYSTEM ES-6
MAGNETO IGNITION
Checking the exciting coil:
Disconnect the plug connection of the
black/red cable and measure the
black/red cable against ground with the
aid of an ohmmeter.
Desired value: 900 ± 100 k Ω at 20°C
PULSE GENERATOR
Disconnect the plug connections of the
blue/white - green/white cables and
measure the cable against ground with
an ohmmeter.
Desired value: 340 ± 50 Ω at 20°C
IGNITION TIMING
ADJUSTMENT
The ignition point shall be
adjusted when the engine has
reached its operating
temperature. Use a stroboskopic lamp
for the ignition point checking .
Procedure:
Mark the engine case with an ignition
marking.
Unplug the spark plug connector.
Screw off the spark plug.
Insert tool in spark plug hole until it
meets the piston.
Turn the magnet wheel to the right until
the piston reaches its top dead center
(TDC).
Mark the magnet wheel with a marking
opposite to the engine case marking.
Turn the magnet wheel to the left until
the piston reaches the TDC again.
