Generator power is no longer
sufficient to supply all consumers
and charge the battery. In order
to ensure that the engine can
be started and the motorcycle
ridden, the onboard electronics
switch off the electricity supply
to the onboard sockets and the
auxiliary headlights. In extreme
cases the seat heating and the
grip heating might also be shut
down.
Possible cause:
Too many consumers switched
on. On-board system voltage
tends to drop particularly at low
engine rpm and when the engine
is idling.

ous motorcycle systems such as
lighting, engine or ABS. This can
result in dangerous driving situa-
tions.
Do not continue riding.
The battery is not being charged.
If you continue driving, the mo-
torcycle electronics will discharge
