Sudden electrical failure
Returning from the dealer after my 2004 R1150R 30K service, the engine quit and wouldn't start - wouldn't even crank. After 10 minutes on the side of the road, attempting to start only caused some audible clicking (fuel pump?), and the tach needle jumped to 4000 RPM. Huh? I'm thinking the charging circuit might have failed, but there was no battery light prior to the engine quitting. Can't think of anything the dealer might have done to cause this, except they did replace the license plate bulb ($20 LED) which appears to be the only "electrical thing" they did. I appreciate any ideas as to what is going on here.
Sudden Electrical Failure
There was a Service Bulletin for the R1150R for zip ties on the front wiring harness being too tight and breaking wires. It was for the harness that goes around the steering head which contains all the control wires. You can find more info at
Hope this helps.
