This happened yesterday as I was on a very bumpy dirt road. The display went dark but the motor was still running, headlight was on, but no turn signals or anything from the display. All fuses in the glove box checked good, I removed the handlebar cover and the plug into the display was intact, I remove the 2 fuses under the seat and they checked good also, where do I look next?
TIA
Tony in Tn 07 GTS 250 with 51k on the odometer

I have a spare battery ànd a test light with an alligator clamp. I put the clamp on the battery and one blade of the fuse on the other post, then I touch the other blade with the point of the test light, the light comes on every time. Is this an adequate test method?

A test light is a good method. I asked because some people think looking at them with their eyes is an adequate check

Next thought:

Unplug each fuse one at a time and check that you've got 12v in the fuse socket on one side (trial and error for which side).

Do the warning lights work?

Is the screen backlit? and does the backlighting work - just not the actual display?

Thanks SteelBytes
It was a bad wire behind the fuse block. All better now
