Did my first set of electrical fuctional tests this weekend. I first spent a good ammount of time checking everything with a multimeter with the power off. I then powered the system (no avionics connected) and check everything to make sure the power was going where it should when it should.
Only ran into two issues, niether are hard to fix.
1: I had swapped the coil connections for the Bat and Start relays (woops), easy to correct.
2: There is a short in the pilot PTT circuit. I'll have to dig into that.
Otherwise everything worked as it should. I have more testing to do, but it is getting there.
I spent a few minutes wondering what the big "E" in the upper right corner of the EFIS meant. Was it a warning or connection problem...couldn't find anything in the manual. I then realized that the "E" is on the plastic screen protector...haha
