OK, I'm ready to eat a little crow! Had very little time Friday evening
when tried to start for a short run with cowl off to check my new
instrumentation. No start. Sat had a few minutes, pulled a spark plug and
no spark. Checked and there was voltage on the D pin of the coil plugs.
Sun afternoon I noticed there was no fuse in the primary injector slot
and that is where I also power pins 33 and 34 on the EC2. Must have
pulled the fuse when messing with hooking up the instrumentation last
week, but for the life of me can not remember doing it! Had to have had a
real SENIOR  MOMENT. Anyway plugged a fuse in and the NOP disappeared.
Rolled the airplane out and it started right up. 

Now maybe there is a good side to this story. Does anyone know if pin 33
powers one EC2 processor and 34 the other? If so than I am darn well
going to hook up a separate line and fuse to get REDUNDANCY for the EC2
after all the fuse/CB talk last week. Tracy's wiring diagram shows one 12
volt supply and then splices a line off by the pins, but I changed from
that mode to two lines with fuses every chance I knew about.

Bernie, hoping to make Lumberton but we'll see how the next couple of
days go
