ELECTRICAL SYSTEM ES-7
Measure the distance between the two
markings.
The overlap point is the actual TDC.
Connect the stroboscopic lamp and start
the engine.
Turn the setting wheel of the of the
stroboscopic lamp until the TDC
marking on the magnet wheel is
congruent to the TDC marking on the
engine case.
Desired value: 17° (1800 rpm)
STARTING MOTOR
Connect a fully charged starter battery
and measure the engine capacitance.
Current consumption: approx. 20A
Special tool: AB-239917
STARTING MOTOR
RELAY
Connect the starting motor relay 30+
contact and the ground contact to a 12V
current source [(+) green/red;
≡ yellow]
and measure the continuity between the
two screw terminals.
Continuity -> okay
No continuity -> not okay
Measure the resistance:
Green/red:
Yellow: 3.8 ± 0.5
