Thanks Bruce. My approach is either an aluminum wheel with 36-1 slots or a white drum with 36-1 black stripes, and an reflective optical sensor. That will give me a TTL block signal that looks a like what a VR produces. If a zero crossing is required then a series capacitor can convert the TTL signa...

I am looking into alternative options for sensing crank position for an engine where a regular 36-1 trigger wheel is not an option. What does the MJ look for in the VR signal? Is it amplitude? Zero-crossing? Edge? Appreciate a hint in the right direction.
