First step: Check fuse F5.bugged said:On board computer has been blank (no readout) since I changed the battery. Have tried re setting following the owners manual but NO zip zero results. Any suggestions on how to make this little guy come alive??

I did check fuse and it is OK or intact.Next!

Never trust your eyes for fuses on this bike. Always, always, always check with a VOM. And then replace it anyway. Seen them where they were good to the eye, good with a VOM, and the bike acts funny when it is running.

Thanks again for response:I have done that several times (disconnected battery) knowing that most puters will reset themselves if power is interrupted.Any further suggestions?mneblett said:Ok-- fuse F1 next.
I expect this fuse will also be ok. Next step after that is to disconnect the battery for several minutes, then reconnect and check the BC.
Bummer. Last thing I can think of is to check whether you have voltage at the BC harness. If you want, I can check the electrical schematic at home tonight to tell you which are the power and ground lines to check. Unfortunately, the connector is under the left side of the nose fairing, as shown in the attached pic (above the black box. I doubt it will be reachable without removing the nose (*maybe* by removing the dome over the dash and reaching down into the nose, but I doubt it; fortunately, nose removal isn't that hard). One way or the other, the nose probably will have to be removed, because if power and ground test good, I believe you'll be in the market for a replacement BC unitbugged said:Thanks again for response:I have done that several times (disconnected battery) knowing that most puters will reset themselves if power is interrupted.Any further suggestions?

Thanks Again Mark, just realized that the OBC has lost it's illumination when the ingnition is switched on. Is this a possible clue that somehow the OBC has lost one or more of it's inter connections?? Power? all fuses prove to be ok Is there a wiring cable connection somewhere that could be open and I can check?mneblett said:Bummer.

Loss of illumination is pretty suggestive of loss of all 12V to the BC. The question is whether the power loss is on the bike side of the BC plug shown on the pic, or inside the BC unit itself -- which unfortunately still requires a voltage check at the plug.bugged said:Thanks Again Mark, just realized that the OBC has lost it's illumination when the ingnition is switched on.
