Way to hang in there Brian. Looks
like persistence paid off. You must feel great.

Subject: [FlyRotary] CAS
polairty/Problem solved
I installed some new connectors for my
CAS that I got from the Madza dealership, they were salvaged from a junk wiring
harness, so don't ask me a part number. Anyway, I had the polarity reversed on
the CAS that senses once per revolution.
After changing it, I was able to get up
to 7100+ RPM without any stumbling, and I didn't go any further because the
brakes wouldn't hold on pavement. (That is with a 68 dia x ?? prop, just
for ground test purposes) For future reference, on the sensors, the side
of the sensors that are to the left, when you are looking at the front of the
engine are the side that have the lead that is common to both sensors. My
engine didn't have one of the CAS connectors, so I used the small female slot
connectors and RTV. Well, you have a 50 percent chance of getting it wrong that
way, and of course I did.
