Please respond if you're NOT GOING TO HAVE A 1200GS FPS FAILURE

When my FPC died in Australia (original 2004 design) I pulled apart the circuitry through curiousity(encapsulated in silicone rubber) and I strongly suspect the capacitor had failed as it fell apart. It's probably the hottest running component which is why it has the heatsink and fins.

There were a few small power handling IC chips on the small circuit board but it was definitely not for home repair unless you were good with electronics, had the required test equipment etc etc. Easier to just replace it with the 'upgraded' item (which has apparently been upgraded again - black painted item).

I took the advice on this forum and cut off the blue connector which links the (now dead) FPC to the fuel pump, then made up a 'flying lead' to plug into the accessory socket. If my FPC goes again I will use the home-made lead to run the fuel pump and get me home/to a dealer. If that doesn't work I'll use Carole Nash helpline to get recovered.

If you are that worried about failure, ask your local dealer if they have any failed FPC (or ask to have on put aside next time they get one) then you can cut off the wiring connector and make your own 'get you home' lead up.

HI ADAM i could be wrong about this i think i remember reading somewhere on another thread that the fly lead you have made up will trip the standard socket as the pump draws 5amp might be worth checking out, still your doin better than me cos i aint got around to it yet!! (a post by wapping i think) cheers

I also read that, but I'm too lazy to take off the tank side cover and try it out for sure on my own bikes CANBUS. Thanks for letting me know though.

My plan was to be 'plug and play' via my beak accessory socket, saving me from removing the seat ( a pain when you've strapped a bag across the passenger seat). It's also long enough to reach the under seat socket for other riders without the beak socket, should I be riding in company with another 1200 that fails.

If I can't use it via the accessory socket as planned, I'll simply pull the cigar plug off the end, twist the wires and put it across the battery terminals instead. It'll get me (or someone else) home should the FPC fail. Having been stranded once, I don't wish to repeat it for the sake of a bit of wire.

"I'm NOT GOING TO HAVE A 1200 GS FPC FAILURE" if I do, I'll fix it with a bit of wire

I was chatting to a BMW parts manager this morning, and he told me that some of the screws that hold the FPC in were too long on some of the bikes. This meant thet the screws bottomed out before the seal was compressed enough, and with water ingress the unit failed. Though he also stated that some of the failures would be pure electronic, electronic components will fail at sometime. Had a HID light ballast fail recently, replaced pdq -Thanks Les for such a quick service.
