    Anyone got one of these?

    It has a mind of its own,
    Fuel was never showing on it, i've had it flashing once when I connected a wire to some metal on the Bike but other than that it hasn't worked or shown up.... which is fine as i've been working our my fuel from my miles.

    Was out yesterday, all of a sudden the speed stops working, I pull over, put the Bike on the stand, check the Magnet and Sensor, all looks fine, checked the back of the unit incase the connection was loose, it was fine.......

    Today, took the casing off the Bike, noticed some connectors (which I used to link the wires together) were abit rusty probably due to me tipping the antifreeze water down there by accident, so I changed those connectors, checked to see if any fuses were blown... all fine, I did notice the wires for the left and right indicators from the Speedometer arent connected to anything though, when I bought the Bike, when indicating right the light on the unit would flash, but it wouldnt when turning left, now it doesnt work at all, but im not sure what wires they should be connected with, for the right one to stop working all of a sudden would mean a wire has come loose? but theres no loose wires anywhere, all the unused ones I have put connectors on the end of them, so abit confused with that, but again not sure where they go.... theres alot of unused wires!

    I Googled the wiring diagram for the Speedometer and labeled the wires (not shown in the photo)... but I dont have any diagrams for the Bike itself and remembering from last time when I had to sort them all, I think they're abit mixed up, so im not sure whether the previous owners used any old coloured wire for things....

    I tried to Google the diagram for the Stage6 Switch unit but found different answers, and its all a total mess wire wise so I dont even know where to start! all that works on the Speedometer is the rev counter, something I dont even need, basically just need the speed and miles working, but its stopped all of a sudden while out riding and im not sure why!

    Haven't checked the earth yet, i've left the Bike, will leave it a few days as it's really annoying me!!!! so going to chill for a few days and then go back out there next week and sort it out.

    The Fuel one never worked, the whole Bike wires are messed up, will have to take everything off the Bike and follow the wires everywhere and label everything, I found the diagram for the Speedo wiring and i've labeled them, but still im not sure whether they're correct as the Bike wires I think are messed up, and the only thing working on my Speedometer at the mo is the Rev Counter... no fuel, no lights, no speed, no miles.

    The actual 4 wires from the Sensor to the socket to the Unit is fine, 4 wires in a cover, nothing split or anything, so abit weird on why I was riding and then all of a sudden the speed/miles stopped working, I cleaned off the Magnet and made sure the Sensor was as close as possible but still nothing.
