Instead of attaching a slew of wires with associated fuses to my battery posts, I decided to install a Blue Sea Systems 5025 - 6 Circuit Fuse Block with Negative Bus on my R1150 GS Adventure. I also installed the identical unit on a friend's R1150 GS. The chosen location of installation of the fuse block makes for easy access as well as placing the unit next to the battery; a logical location.
A slightly smaller unit is the Blue Sea Systems 5028 - 6 Circuit Fuse Block without Negative Bus, but the 5025 fits nicely in the available space so I went with it instead. Besides, I wanted a negative bus on my fuse block.
The fuse block is mounted on an aluminium plate that was shaped, bent, drilled, glass beaded and then mat clear coated. It attaches to the bracket that holds the diagnostic plug using two rivets.

My Blue Sea Systems fuse block is wired directly to the battery using 10 ga wire with heavy duty eye lugs soldered to each end. Each wire is then covered in plastic spiral wrap for added protection, not that it is required in my installation. Considering how the main power wires are routed and protected in my installation, a main fuse for the fuse block wasn't used; BMW doesn't fuse the main power feed from the battery to the alternator or starter either.
My Blue Sea Systems fuse block is HOT all the time which is the way I wanted it, otherwise a relay capable of handling a continuous current draw would be inserted between the positive of the battery and the fuse block.
Connected to my Blue Sea Systems Fuse Block are:
- Hella FF50 driving lights,
- auxilliary power connector (cigarette lighter outlet),
- YUASA Battery Analyzer (connects to my YUASA Hot Shot battery maintainer and powers my electric vest),
- Datel LCD digital voltmeter, PN: DMS-20LCD-1-DCM.
