Zitat von skinneroo im Beitrag #1 I would think the bmw socket on the outside just below seat would be switched and not monitored by the Canbus, tap into that, then you can relay direct from battery. Ged 2019 R1250 GS TE Black |

Pretty sure that the DIN socket near the seat is CAN bus controlled - you'll need to wire direct to the battery e.g. with an SAE connector on a fused lead (hint - use the "jump start" pole as the +ve connection to save having to connect to the +ve on the battery itself).

Ctek direct to battery (or remote posts as said above) is fine. |

"There are also 2 real fuses under the rider seat in a black pod that looks like an old 35mm film canister. These are not canbus controlled. One is always live, the other is switched. I have used a piggy back fuse on the switched one to give me an extra accessory socket. |

It's now wrapped in self-amalgamating tape as the additional fuse makes the lump too large to refit in the pod. You can see the one half between the tank and that large, silver module. I've put a dayglo yellow loop over it. It's under your right buttock as you sit on the bike. |
Zitat von wessie im Beitrag #4 Yes, you are correct, it's just a trigger. I will try to posi tap into the live on either the din socket or the one you have piggy backed, whichever is the most accessible. (what happens if it does disturb the canbus?) Many thanks |

Zitat von skinneroo im Beitrag #8 The ECU (electronic control unit) communicates with the rest of the bike via a CANBUS (think of it a bit like the phone line or fibre optic cable your internet arrives through). Instead of fuses, the ECU detects the current being used in each circuit. The ECU can turn circuits on and off as it wants. The current sensing is what allows it to identify a fault such as a blown bulb or short circuit. The accessory socket is switched on by the ECU only when the ignition is on. Therefore, unless you use a CANBUS compatible charger, you cannot charge the bike via the accessory socket. This special type of charger is able to talk to the ECU to wake up the socket to allow charging to take place. If you connect your charger direct to the battery you can bypass the canbus. The RS battery is not very accessible so BMW has equipped the bike with what are described as Jump Start posts in your manual. These are under the triangular plastic cover by your left shin. These are effectively battery terminal extensions which you can use to attach a charger's fly lead or an accessory like the Fuseblock. |

If anyone wants to buy an "old style" BMW charger (i.e. one of these https://www.adverts.ie/accessories/bmw-m...charger/5806763) in excellent condition I can do you for £20 +P&P.
