12. EFI ECU POWER & SIDE STAND RELAYS
There are two identical relays located inside the Electricals box LH side (on Bullet EFI & Classic EFI models) and on the
battery bracket inside the LH panel (on Continental GT models).
SPECIFICATION
Operating Voltage : 10 V to 16 V
Operating Temp : - 30 ° C to + 120 ° C
Fuel Pressure : 343 Kpa
Resistance : 10.3+0.5 Ohms
The EFI ECU Power relay supports functioning of the ECU and fuel pump. The Side stand relay provides the inputs
regarding the position of the side stand to the ECU. In the event the side stand is NOT retracted and the motorcycle
is attempted to be started, it signals the ECU which cuts off the fuel supply thus preventing the engine from starting.
13. ROLLOVER SENSOR
The rollover sensor is located on the frame under the seat.
The rollover sensor, also known as a “banking” sensor, is a safety feature. If the banking angle of the motorcycle goes
below 60
o
OR in the event of an accident causing the motorcycle to fall over on either of its sides with the engine
running, the rollover sensor will “command” the ECU to cut off both the fuel supply and ignition, thus stalling the
engine to prevent any further damage from being caused by the engine that may be running with a stuck open throttle
and the gears engaged.
To re activate the system, the motorcycle should be made upright in its centre stand position, the ignition switch and
stop switch must be switched OFF and switched back ON after a few seconds. This will help to RESET the rollover
sensor.
