If possible, protect by enclosing in clear plastic.
For example cover in self-adhesive plastic or laminate.
Alternatively insert in a suitable thin clear plastic wrapper e.g.
from a personal organizer add-in.
Place under fusebox lid and forget until/if required.
The diagram applies to the following BMW motorcycles.
It also applies to other models with small modifications.
Fuse 3 remove RID and add clock.
Fuse 2 add backlights for clock and tacho.
R850/1100RT (non-police) models
Fuse 8+ blue 15A for the radio.
Fuse 4 add windshield motor.
Fuse 3 add second accessory socket, radio and windshield motor.
The wiring diagrams are not included in the BMW Workshop manual.
Instead there is a separate publication available from any
BMW dealer. BMW part number 01 99 9 798 708.
These are black and white and have a multi-language key.
The Haynes manual includes a color wiring diagram.
The diagram includes corrections and further details
not printed in the BMW Workshop manual nor the Haynes manual.
For example it lists the individual components on each fuse
Another example is that the BMW manual refers to the "fuel level damping" relay.
More accurately this is the "fuel light damping" relay.
Damping for the RID fuel gauge does not involve this relay and
is performed by a microcomputer in the RID.
Relay 4 Load Relief
The load relief relay is actuated when the ignition is on and
the starter button is not pressed. This means current flows to:
the headlights (through the headlight switches)
fuse 2 (through the right side light switch and ignition switch) and
the instrument backlights and tail and side lights.
Pushing the starter button releases the load relief relay which
cuts the current to the above items.
The bottom ABS warning light is fed through fuse 1.
The top ABS warning light is not fused and goes through relay 8 ABS warning.
There is another ABS relay under the tank that is directly connected to the battery
and not fused!
Some of the fuse ratings BMW specifies are odd!
For example fuse 1 and fuse 2 both have a 15A rating but 4A would be fine.
On the other hand fuse 7 is very close to its rating at 4A and perhaps
15A would be better.
(Possibly down to the time-honored
BMW tradition of re-using components straight from previous models without
considering their usage on the new model.)
The two empty compartments in the fusebox can be used to store
spare bulbs in foam or bubble wrap. For example two turn signal
and one rear bulb.
There is not enough space for a spare headlamp bulb. However,
one can be carefully fitted under the seat at the back of the
tank by the battery.
Hazard Warning Lights
Two neat features that many owners do not know.
If the hazard warning lights are switched on, they
stay on when the ignition is turned off.
The hazard warning lights can be switched on by pressing both left and
right indicator buttons simultaneously. The hazard
warning lights then remain on while both buttons are held down.
When riding this saves fumbling for the switch.
Note - this does not work with the switchgear on the
