BMW R1200R R1150R/T F800 K1200R R1100R/T R1250R RnineT Message Board

This morning I noticed my hi-beam is out. I hit the autoparts store during lunch and found the right replacement, but before I tear into this, I was reading the manual and they say to disconnect and insulate the ground from the battery.

I assume is the small, "3rd" wire connected to the battery posts? By insulate do they mean make sure it doesn't touch anything else while it's disconnected?

It seems pretty straight forward, I had the headlight apart looking at it (and it didn't fall apart going down the road after lunch), but I don't want electrical problems.

I'm not sure what the directions say, but it's sensible common practice to take the battery offline before you start working with the electrical system. This would include bulb replacing tasks...

...So you have to take the tank off to replace a headlight bulb???!!!

No, you don't have to take the tank off (this is an R1100R we're talking about). Take the rider's seat off and the battery terminals will be accessible.
