28AAD panel wiring

I’m using MYRO’s old instrument panel in 28AAD, my French Weedhopper. The one that came with it is full of holes because its instruments were all removed and the one I designed for MYRO was pretty good, worked well and is still in good condition. However, as I’m not going to install MYRO’s electric fuel pump in 28AAD as I think that it’s just dead weight, I have to make a minor change to its wiring.

I originally fitted three Aux power sockets in MYRO’s panel that are all live as soon as soon as you switch the Master on, whereas when I designed 56NE, my X-Air’s panel, I installed a second switch to control its Aux sockets. The obvious way to update MYRO’s panel is to use the fuel pump switch to control its three Aux sockets and that’s quite easily done, by switching over the fuel pump 12V+ to power the aux sockets, as shown by the following diagram. Even the fuses still work!

It won’t take very long to do so I’ll do it later and then the panel will be ready to fit in 28AAD at any time. It’s still missing some instruments but they can be added later if necessary. But first I need to patch the mounting holes in MYRO’s old panel top as I mentioned in my previous posting.
