Electric starter system 950 Adventure

NOTE: the starter system is equipped with a safety feature.
You will only be able to start under the following conditions:
– If the gnition lock is in the ON position
– If the emergency OFF switch is in the ON position
– If the transmission is shifted to neutral or the clutch is pulled
How the starter system operates:
Battery voltage travels from the battery
the auxiliary starter relay
5
The ground supply to the coil of the auxiliary starter relay takes place if at least one of the following conditions are met:
– Transmission is shifted to neutral (neutral switch
against the ground)
– Clutch is pulled (clutch switch
NOTE: if these conditions are met, the load contact from the coil is closed (nonrecurring "click ").
When the tip switch is actuated, battery voltage flows through the closed load contact of the auxiliary start relay
9
of the start relay and from there against the ground. This causes the load contact on the start relay to close and battery
bk
voltage to flow via the start relay contact to the starter engine
The diode is one of the electric starter system's important safety features which prevents the starter engine from being
bm
actuated although a gear is engaged and the clutch is not pulled. The diode does not allow current to flow when the side stand is
folded down, in other words, the auxiliary starter relay will not have a ground connection via the side stand switch.
If the clutch is released with the engine running and a gear engaged although the side stand is folded down (driving off with the
side stand folded down) the ECU will not have a ground connection through the pink cable, the voltage will increase to
over 2.5 volts and the ECU will break the ignition, immediately causing the engine to stall.
An alarm system (accessory) can be connected to the BA/BF
alarm system is installed.
