I have an 8 pin HEI connected to a distributor on the bench. I’m using the information in the manual located here as my guide but can’t seem to get the speeduino to light up when I spin the distributor with a drill.

Unfortunately I don’t have an oscilloscope. After spending the morning trying to get Ardustim to connect to the UNO I’ve given up on that for now.
When I connect a multimeter to the R and G I get 1.88v while spinning the distributor with a drill. I imagine this should be reading 5v…?
+Is connected to battery positive
C is connected to battery ground
R is connected to pin 25 (crank / VR1+)
G is connected to pin 9 (sensor ground)
Pin E and B are not connected (I plan to connect these once I have a signal).
I’ve set JP2 to Hall and JP4 connected (ie, 5 volt pull up).
I’m wondering, are my connections correct, have I missed something, could the ignition module be faulty…?
