I am building and MS1 v2.2.
The MS1 Extra Ignition Hardware Manual provides 2 different set of mods to the board for hall sensors depending on whether the tooth coming in front of the sensor takes the voltage up or down.
I have bought a Honeywell Microswitch Geartooth Sensor 1GT101DC. Link below. It is described as current sinking. Does that mean the volts are up with no tooth and when tooth comes in front the the volts go down?
Secondly, in the diagram in MS1 Extra Ignition Hardware Manual it shows the 5v supply, presumably from pin 26, routed via a 10R. R will be resistor but does the 10 mean 10 ohm? http://sensing.honeywell.com/index.php?ci_id=50300
