Checking the auxiliary starter relay
– Dismount the auxiliary starter relay
1
.
NOTE: orange, yellow, red and white/red cable colors.
– Connect the auxiliary starter relay (see drawing) to a 12 V battery,
making sure you hear the relay switch (nonrecurring "click").
NOTE: the 12 V battery must be connected to the two terminals to
which the orange and yellow cable colors are connected when the plug
is connected.
– Use an ohmmeter to measure the continuity between terminals

Functional check of the auxiliary starter relay
– Pull the auxiliary starter relay out of the bracket.
– Connect an ohmmeter or continuity tester to the cable of the
auxiliary starter relay (red and red/white cables).
– 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.
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
is engaged. If not, check the diode and neutral switch
NOTE: You will hear a faint click when the auxiliary starter relay
switches. The ohmmeter or the continuity tester will display the
continuity when the auxiliary starter relay is switched on.
Checking the diodes
NOTE: Diodes only conduct the current in one direction. They block in
the other direction.
Diodes can have 2 defects:
– the diode has no continuity.
– the diode has continuity in both directions.
Various malfunctions can occur, depending on the type of defect.
Each diode
2
is plugged into a bipolar connector (connector AI)
Functional check:
– Connect a suitable ohmmeter to the diode and check the diode for
continuity.
– Connect the ohmmeter in the other direction and check if the diode is
blocked.
