Thank everyone for all the tips. I think I used them all. Did hook up a battery today (all through a 5 amp fuse)and everything seems to work fine. EM2 lit right up and all temps looked right, tach showed 0, pressures 0. flaps work, under carrage works, fuel pumps work. Havent even blown the fuse. But only turned on one thing at a time. Even backup camera worked like a charm. Can see both landing gear. I power the EM2 off the main bus, and power the EC2 off a flight critical bus. With the EC2 off the EM2 showes the RPM with NOP. So far, so good. I havent done anything yet as far as trying the injectors or coils. I dont have a real battery yet. I'm using my 7amp 12V hobby battery at the time. I'll get a real one next weekend and go a little further.

 

Thanks for everybody's help
