– Perform the tests in the specified order. The auxiliary starter relay
must switch under the following 2 conditions:
– Slowly pull the clutch lever with the gear engaged. The auxiliary
starter relay should switch at half of the lever travel (ignition and
kill switch on).
If not, check the clutch switch. Observe the idle indicator lamp, it
may not light up. If it does, check the diode.
– Switch the transmission to neutral with the clutch released. The
auxiliary starter relay should switch on and switch off when the gear
