The wire in "B" does continue on to the ign module?

Its any help you can borrow my caspers tool?

His car runs...therefo re the voltage has to be rising and falling.  B goes to a buffer amplifer in the module

Hall sensors can show funny if they don't have their normal load attached- why I asked.

Good point...

don't disconnect the cam sensor while checking voltages....se e the factory diagram at the bottom of the page  http://www.vortexbuicks-etc.com/cam_sensor.htm (http://www.vortexbuicks-etc.com/cam_sensor.htm)   The voltage is checked with the cam sensor connector plugged in
