The disc bolts are in good condition and steel standard ones . i have just fitted a new sensor . it comes up with an 036 code fault before and after the new sensor which is speed sensor disc etc. but the wiring loon is brand new and only 1000 miles old . genuine Ducati as is the sensor .. so im thinking the clocks are at fault
they did give some random readings for a little before it all packed up ... going from 0 then back to the current speed and jumping about almost like a shorting wire
or damp etc
