5.3 Ignition settings 5 SETTING UP A BASIC CONFIGURATION
using the standard cam input, a voltage of ~0V here requires the HIGH setting and a voltage of ~5V here requires
the LOW setting, as the MS3Pro input conditioner inverts the signal.
Now rotate the engine backwards a full revolution. The cam sensor will be opposite that previous window/tooth/vane.
(If there was a window before it must be a vane now and vice versa.) You can use a volt meter to confirm the output
has changed its state.
Example of a distributor converted to a cam sensor, using a commonly available gear-tooth sensor.
