I leave the ignition in the "on" position with the
motor not running? If yes, for how long?
Yes. ...for as long as necessary.
[ Applies to systems built after
October, 2008 ]
If the key is "on" and the motor is stopped there
will not be any damage to any of the components.
Modules coded "E4" (engraved in the potting
compound at the back-end of the module), in production after
October, 2008, have an automatic "timeout" feature that interrupts
the coil current if the key is on and the engine has either not
been started or has subsequently stopped after 30 seconds. The
timeout automatically resets itself when the system detects crank
rotation - you don't have to reboot module power to start the bike
after timeout - just kick or e-start.
