Repair manual KTM LC8 Art.-No. 3.206.035-E
Starting system 990 Super Duke
NOTE: The starting system is equipped with security features.
The motorcycle can only be started under the following conditions:
– Ignition lock in the ON position
– Emergency-off switch in the ON position
– Transmission in the idle position or the clutch pulled
– Alarm system deactivated (if installed)
990 Super Duke starting system - mode of operation:
Battery voltage flows from the battery
1 via the ignition lock 2, fuse 3 and the emergency-off switch 4 to the tip switch 5.
The coil of the auxiliary start relay
6 is supplied with ground if at least one of the following conditions are met:
– Transmission in the idle position (neutral switch
7 closed, current can flow via the diode 8 and the neutral switch to chassis)
– clutch pulled (clutch switch
9 closed, current can flow via the clutch switch to chassis)
By pressing the tip switch
5, battery voltage will flow to the coil of the auxiliary start relay 6 (via the bridge connector bk or the
alarm system - if installed; for accessories, see alarm system) which picks up the load contact, as well as to the coil of the start
relay
bl via the closed load contact and from there to chassis. This causes the contact on the start relay to close and battery
voltage to flow via the contact on the start relay to the starter engine
bm.
The diode
bn is one of the starting system's important safety components. It prevents the starter engine from being actuated even
if a gear is engaged and the clutch is not pulled.
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 interrupt the ignition and injection and immediately cause the engine to stall.
