Thanks Ross, I am using magnetic sensors which dont use a power supply however I have found a drawing for motec - magnetic sensors showing trigger voltage levels as
0.25V min <500 rpm
1.40V min >500 rpm
So 0.4V should be O.K. at crank ( rpm shows 190 with plugs out )
It would be good to see a scope capture showing showing correct ref / sync set-up if any one has one on file
