Wire AH, Canopy clearance

I wired the pwr/gnd to the artificial horizon plug and spun it up. (I wired the ground to the wrong pin at first.) The OFF flag shows until the gyro is completely spun up, which takes a little while.

Ray had mentioned to Bill and I to be careful how high we put our radio's in the radio stack. The canopy frame and tip-up brace could interfere/rub on whatever is up top if you aren't careful. I forgot all about this when doing up my radio's, so I had Sandi come out and help me set the canopy on. My audio panel tray is 1.5" from the top of the panel and it is approx. 2" from the rear of the tray to the sub-panel. With the canopy in place, I could just get a finger between the tray and the reinforcement bracket on the canopy. Ray said he put his at 3/4" from top and the canopy frame was hitting the wires coming out of the back of the tray. Since my radio's are flush mounted, my tray extends back farther than normally mounted trays.

TIP: Plan for this! If you put a full length piece of avionics at the top of your stack, you could run into trouble. I would suggest marking a line on the sub-panel where the tip-up channel runs. This will tell you how high you could mount something.

I made a list of about 18 electrically related things to do but just didn't feel motivated to do them, so I went in for the evening having only crossed off one.
