BMW R1200RT/R1250RT Forum

I've disconnected my battery on my new RT1250 to fit some accessories. Connected everything back up but the bike won't start. What could it be?

Have you checked everything?

Is it in neutral etc

Disconnecting the battery and reconnecting it should stop it starting.

Check your connections too

Yea checked all connections. disconnected the accessories and put it back the way it was & still won't start.

Is the bike turning over?

No. The Dash doesn't start up either.

That suggests to me that the battery is not connected properly somewhere or the main fuse is popped

Pull the battery and check the polarity and also check the main fuse

Ok, sorted..a loose connection. Rather obvious. Thanks for your reply!

Hi, can someone tell me where the main fuse is? I've looked online at the fuse box and can't see a "main fuse" listed. Thanks Pete

no fuses. The bike uses canbus system

Fuses under the rider’s seat.

well blow me . I always thought everything was run by the canbus. My 07 has any fuses

That would stop it starting?
