Checking the auxiliary starting relay for faultless
operation
Preparation:
– Connect an ohmmeter or a continuity tester to the cables of the
auxiliary starting relay (colors: red and red/white).
– Perform the tests in the order indicated below. The auxiliary starting
relay must respond in either of the following two cases:
● Put in a gear and slowly pull the clutch lever. The auxiliary starting
relay should respond when the lever is pulled approximately half of
the overall distance. If this is not the case, please check the clutch
switch. Keep an eye on the neutral control lamp while performing
this test. The neutral control lamp should not light up. If it lights up,
check the diode with the cable colors yellow and green/black.
● Switch the transmission to neutral without previously pulling the
clutch. The auxiliary starting relay should now connect and be
tripped as soon as a gear is put in. If this is not the case, please
check the diode in the connector with the cable colors yellow and
green/black and the neutral switch.
NOTE: Connecting of the auxiliary starting relay is always accompanied
by a faint clicking sound. The ohmmeter or continuity tester indicates
continuity while the auxiliary starting relay is on.
