I posted this over on the general forum with no luck so I'll try it here.


While on our vacation up in Tenn ( we are still hear ) we got caught in the rain going to Maggie Valley and my speedo quit working and the F1 light came on. After a few hours it must have dried out and it started working again, that is until I washed the bike this morning. Again speedo not working and F1 light on for about three hours and then out of nowhere its all fine again.So I'm guessing it must be some kind of switch getting wet , any ideas on which switch or what I need to look for.

I'm thinking about either brake or cruise switches on the handle bars. When it happenes the cruise won't set , the blinkers won't cancel , the remote dose not work along with the speedo.The only good thing is the odometer dose not work either so I did'nt put any miles on the wing while this happens

BTW this is the first time this has happened, bought the wing new on June of 07 and now with 74,000 miles on it ,living in south Florida it has been on too many rain storms to list and has always been washed with soap and water after each ride. Thanks for any ideas and help..

Do you have a speedo correction device on it? If so, those can have issues and kill your speed signal coming from the speed sensor. Another possibility is water getting into the speed sensor's connector or the connector on up the harness from it. Here is a diagram that shows it's location as well as the route the harness takes to the connector close to your right knee while sitting on the bike. The connector is in the rubber boot at the top right of the picture. The loss of this signal will cause all of your symptoms because all of those systems need the signal as a reference for the bike's speed to work properly. Your remote failure may be something else.

Happened to me in the rain last week. Light went away after it dried out. I don't have a speedometer correction device so I will be checking and silicone greasing the connector under the faring next time I do the air filter. Sooner than that if it happens again.

If you don't find any problem at the sensor or the connector in that boot you can follow the wire, pink before the connector and white/black after the connector headed to the ECM and the gauges. At some point in the harness it splits with one of the those troublesome terminal blocks. That could be the culprit if everything else looks good.

I've had the problem three times and have had a speed healing device installed for 7+ years. The first time was in the summer of '10'.

The first and third times happen the next morning after having ridden in the rain most of the previous day.

The second time occured after having ridden in fog for 3 1/2 hours, then stopped for lunch for about 2 hrs. Once the ride was resumed the problem occured and took about 1/2 hr. before it cleared up.

After re-reading the previous posts, I'm thinking the 'speed sensor' area may be the problem area. Don't think it's possible to splash water up in the boot where the connector is while washing the bike.

I agree, the boot is a place that I doubt water or rain could get to by itself, even in a downpour. It is either occuring under the exhaust headers at the sensor or possibly in the harness where the terminal block resides. If someone comes across the location of the block in the harness, let us know where it is and possibly get a picture of it. :thumbup:

You might want to check and see if you have the weather protection boots completely on you information panel or damage to them.

I just finished up a massive troubleshooting of multiple problems with my speedo, tach, fuel guage, turn signals, navi, oh hell the only thing that was working was the temp guage.

Unfortuately mine was caused by a piss poor dealer repair (replaced the Kill switch components on the handlebars). If the connectors on the back are loose or the weather boot is allowing water to get inside it might cause the problem. Just a suggestion here don't shoot the messager.

I finally have the repair done which was to clean all my connectors (the three) reseat connections andweather boots, and OBTW had to replace the wiring harness because they damaged the section that brought all the information up from the rear of the wing. 22 hours of repair time.

But I did digress a bit here.

OBTW, the hint about coming in from the front and making sure the connectors click sure did help.

Wheels49, what code is it flashing? If it really was an injector code, it shouldn't have started back up. Injector codes are fatal failures and aren't supposed to let the bike restart after shutdown.

If it ever does it again, pull over, put it into neutral and put down the sidestand. DON'T shut it down. The FI light will start flashing the failure code in long and short flashes. Take note of how many of each you get and we can look it up to see if it is pointing to the speed sensor.
