I finished up the wiring to the ACU from the radio stack, and also to the E1. That’s about it now for the stack.

The EFIS end… The ACU outputs go into Analogue 1. There are eight required, CDI L/R, Nav pass/fail, GS Up/Dn and GS pass/fail. For some reason, the E1 doesn’t utilise the To/From outputs. I need to read a bit more about this to find out why.

The other thing I did tonight was to tie in all the Grounds for the stack. Then I started testing it. No antennae still. I need the connectors. Anyways, the radio checked out great, and I could send/receive transmissions loud and clear to/from the handheld in the hangar, The AOA voice annunciation worked perfectly, the intercom works great and even more amazing was that there was no smoke! This audio panel has a six place intercom. Perfect for an RV! Maybe I should hook up an exterior set of plugs for ground grew to plug in to!

The one loose ground wire is for the Marker Beacon antenna.
