I discovered that my wiring errors weren't wiring errors at all. After checking all my wiring and finding it right, I deleted all the accessories on the remote for AIU 1 and reloaded them. All of them worked this go round. Second, I discovered I forgot to program one of the tracks on AIU 3, so once I added that, all is swell!!
I also plugged in the Gunrunnerjohn Watchdog Generator on my TIU fixed output 2 for my sidings. When I powered all the sidings, none of the engines started up on applying power just as John designed it for. I was now able to start each engine with the remote individually. Hooray!!
Thank you John, and Thank you Bill Webb for the AIU assistance!!
