Ignition Switched On - Husqvarna RB150 Workshop Manual

E

Ignition switched on

See fig. 3.
The circuit is made via L and B in the ignition switch
S9 and goes via the following components:
• Fuse F1.
• Lights switch S3.
• Operating coil in relay K2.
• Earthed via microswitch S7 underneath the
operator's seat.
When relay K2 is activated, the earthing connection
to the engine stop function in fig. 7 is broken, and
the starter motor function is earthed instead. Current
is supplied also via fuse F1 to the main jet 3 of the
carburettor, which is earthed to the engine.
