DESCRIPTION. This side-stand/ignition interlock system is to prevent starting the motorcycle with the side-stand left down

This side-stand/ignition interlock system is to prevent starting the motorcycle with the side-stand left down. The system is operated by an electric circuit provided between the battery and ignition coil.

Side-stand switch

The circuit consists of relay, lamp, diode and switches and decides to live the ignition coil depending on the position of the TRANSMISSI ON and SIDE-STAND with the neutral and side-stand switches work­ ing mutually.

The ignition coil lives only in two situations as follows:

1. Transmission: " NEUTRAL (ON)" Side-stand: " DOWN (OFF)"

The current flow ® turns " ON" the relay and the ignition coil lives even the side-stand is kept down. This is for warming up the engine.

If the interlock system does not operate properly, check each component. If any abnormality is found, replace the compo­ nent with a new one.

Diode

The diode can pass current only in one direction.

• Check the continuity between CD and ®. If one way conti­ nuity the diode is in good condition.

• Also check the continuity between ® and ® as required.

The neutral lead wire coupler is located behind the battery holder.

• Disconnect the neutral switch lead and check the continuity between Bl and ground with the transmission in " NEU­ TR AL".

The side-stand/i gnition interlock relay is located on the left frame back side.

If there is no continuity, replace it with a new one.
