I am having trouble getting my roll lock to work on my 2009 mp3 I have checked everything I can think of and still no luck. Here is what I have done.
Tone wheel pickups measure 900 ohms and I have cleaned the crap off them
Pressure switch S/C unlocked O/C when pressure applied by hydraulic cylinder
handlebar switch tests ok according to repair manual
microswitch S/C unlocked O/C when moved off normal
Motor works OK when separate 12v applied to terminals
Potentiometer measures 4.26K ohms and and resistance changes smoothly when centre wiper is moved
Also the seat switch measures 3k ohms when seated and 17.5 k ohms otherwise
No warning signals when the ignition turns starts and runs ok on the road
I've run out of ideas I hope somebody else has some. I'm 76 and really need the roll lock its too heavy for me to manoeuvre without it.
