Help with no tach & engine light

[Hoople]

Does anyone happen to know whether this tach works with a pulsating signal like all the older ones or does the ECM send a variable amount of voltage to show the RPM's?

Hall effect 3 wire sensor in transmission. See attachment. Reference voltage,,ground,,& signal output. Not sure but probably reference is +5 volts.
Jack bike up and measure signal output of sensor while you rotate rear wheel.
Voltage should toggle between reference and near ground.

Where is the cam sensor on the newer twinkies?

Late models don't use a cam sensor but I wish they did. Injector and spark phasing is done differently on late model bikes.

Thanks. I was pretty sure I did not see one in there when I was in the nose cone, checking my tensioner condition. I was thinking along the lines of the teeth picked up by the crank position sensor...

Enjoy,
