Mid blat speedo dropped to the bottom of the dial, bounced up and down a few times and then just sat there. Shortly after that went over a bump and it came back to life briefly, then dies again. Odometer display still visible but not going round.
Cables seem secure in the back of the dial, no visual damage to sensor to plug cable on rear right wheel. Not checked any fuses yet as assumed that because LCD was working I have power, but I am happy to be educated on this. Searches suggested when power goes it all goes. Car is 2012 supersport 140 with 2000 miles on it. Not checked the sensor flashing light yet - do these sensors just fail?
Before I run around the whole car with a multimeter, anything obvious I should check?
