Got the GG1 back together finally and tested under conventional. Directions work, motors running together, bell and whistle tone test worked as do the lights.
Biggest problem is wire management. A real headache even in the "roomy" Premier GG1. Had to take it back apart 5 times before I could finally keep wires off the tach strip, no pinching, not crammed between the roof and the top of the flywheel, etc.
Hint: before testing the bell and whistle tone ensure the volume pot isn't turned all the way down First test no tones so back apart it came until the volume control dawned on me.
Probably should have cut off all the wires I didn't use, MARS light, ditch lights, smoke unit, etc., etc. but didn't want to do that on my first one. That's on the "retrofit" list when the BCR2 goes in place of the battery pack.
Tomorrow we load the software and see what happens.
Too darn many wires!!! I'm sure I'll have dreams about wires for weeks.
