Replacement fuel sensor not working - now what?

[MikeR]

My 2018 Buddy 50 (2750 odo) has shown "E" on the fuel gauge for quite awhile, even after I replaced the sensor (and hopefully did that correctly). Hasn't bothered me much because I keep the tank always full, with non ethanol gas.

But now it's time to look into possible causes, and I suppose that my direction should be to learn WHICH wires (colors) I should be looking for, which lead to the gauge on the instrument panel.

The only thing I know right now is that wires to the instrument panel are behind the "Hood", front of Buddy.

Your assistance would be greatly appreciated, thanks!

Pull the headset top and check the connections for the fuel gauge. There are three fine-thread brass nuts that hold the sender wiring to the gauge. I've had the nut work loos and even fall off. Replacement fine-thread metric nuts can be found at ACE Hardware.

Remove the headlight trim first. One screw at the 12 o'clock position. Tilt it out and wiggle it slightly to free the lower clips. Remove the four #2 Phillips screws from the bottom of the headset. Disconnect the speedometer cable at the wheel and push it back up the fork a bit; this will help with lifting the headset cover off. There are (I think) three clips on the pack of the headset and then two in the front, out by the brake levers. These last two are sometimes fiddly, but you can access them with a small flathead screwdriver through the brake lever opening.
