Have you checked the KILL switch

Have a look on the chain gang site - http://faq.f650.com/GSFAQs/
You've asked the question in the wrong section as this is where the modern 650 types hang out but worry not.
Good luck and welcome.

The most likley culprits are the relays that live underneath the cover in front of the battery. One is a load control relay and it has a little capacitator which stores 12 volts and feeds it to the BMS unit for 3 secs or so while the starter is in operation. Or doesnt.

Water can get up into the mounting and corrode the pins and the large square one can just fail .

Intermittenty.

For a couple of years, until it finally stops forever. Dont ask.

Substitution is the only way I know of checking them.

There are pics sonwhere on the 650 single forum on this site of the offending items.

Also check that the wiring harness is not rubbing against the rear of the remote shock adjuster where it crosses over from the frame to the engine - it can be expensive if not found in time.If BMW have a harness to sell you that is.
It is a recall item for Daker owners in the US, but everyone else pays to have it fixed - dont ask .
