Fuel light operation

[Keith Chapman]

Tarka, this is a health warning, This might appear to be a numpty question, so take your blood pressure pills before reading

Right, now to the question, The bike is a 2002 1150. Is there a way of checking the operation of the Fuel warning bulb, may be by earthing a connector some where. I know I could take the screen and other bits off the front and remove the bulb. But I was just wondering if you can force the bulb to light, similar to forcing an oil light on by earthing the lead to the switch without stripping to many bits off.


Ok Tarks it is safe to come out now

Fill a spare fuel container and ride until the light comes on.

If the bike dies before the light illuminates it aint working.

If it comes on, great, you know it's working and you've had an enjoyable time on the best bike around

p.s. If the tank is full to start with you may have to ride 200 miles or more!

200 miles from a full tank to light on - mine doesn't come on until i have clocked at least 300 miles......I must be slow

Keith, this can be done by shorting out (with a bit of fuse wire) terminal 31 (earth) and c (to low fuel level switch) on the dial damping relay (German for low level relay). This is an elaborate box of tricks that ensures you do not get a flashing fuel light as it swills around, and 'samples' every eighteen seconds, so you must wait at least that long for the light to come on. I don't know why they make it so complex, the same result could be acheived with a latching relay. Don't ask me how I know all this.
I have the wiring diagram as a pdf and could email it if you want, it's 1.1mb
