Bord Computer Issue New Member

Greetings, all.

I am proud to say that I've recently added a 00' K1200LT to my herd and it is my first BMW, although I've lusted after them for years. The bike is a low mileage example that I couldn't pass up and it appears to have been well maintained. There are no authorized service points close to my location, the bike came with no owner's manual and therefore, I have ordered a service manual. In the meantime, I am thoroughly enjoying this bike with the sportier handling, more ground clearance and lighter feel, as compared to my late model Goldwing, as well as, the on-the-fly windshield adjustment.

The one (and only) issue that I've had so far is that the "bord computer" shows no sign of life. I've searched this forum for solutions and have tried the suggestion that I found (cold start) without change or success. I've released the catches on the unit but doesn't appear to be enough slack in the pigtail to disconnect completely or clear the dash opening.

I am hoping for advice on where should I start?? I haven't located a burnt fuse and don't have a inkling of which fuse is for what. I hate to start buying replacement parts without trying to narrow down the problem. The bike was traded in at a non-BMW dealership and therefore, don't have a previous owner to quiz.

Any suggestions would be much appreciated.

Thanks in advance,

Looking at the diagram fuse F1 and F5 both feed (one is all the time one is switched power). But based on what else they feed I don't suspect that they are the problem. So either you have a dead unit OR a cable has become disconnected. May have to pull the left side tupperware to access the connector.

Re: Bord Computer Issue New Member

Many thanks, Dick. Your are already my hero.

I've been riding 35+ years and accumulated 10+ bikes (59' thru 08') and a new CanAm Spyder (kind of a bike) and none of them have got my excitement level up near as much as the LT. In the short few weeks that I've had LT, I've made two trips to North Carolina and a trip to northwest Arkansas from Sou. Mississippi riding sun up to sun down. Can't get enough.

I'm low on the learning curve on BMW's but, thanks to you, am on my way now.

Thanks for your generousity.

Thanks to you, as well, John.

I found a link on "tupperware" removal and that will be my next step.
