Spaghetti Anyone?

So I start this 'simple' 30 minute installation that took an hour and a half.

Since I'm not using an actual overhead frame, I have to use cotter pins for the Dzus fasteners to lock it in the framework. I couldn't get that damn pins positioned for the fasteners to turn over. There was virtually no room on the right side and very little on the left.

Fortunately the fit into the holes is tight. I got three pins in and I'd had enough. It's tight though. The wiring really did only take ten minutes or less. The indicators worked great, then I wired the lightplate to the buss.

I throw the switch and the whole overhead backlighting flashed once and then went dark. I thought, "Oh no, not again..."

I burned up another switch. I'm glad I had an extra on hand to replace the bad one. I'm going to be rewiring this on/off circuit to use a high current capacity relay to eliminate this problem once and for all. One of these days I'm going to have to put a clamp on ammeter to this circuit and see what it's drawing. Five amp switches just aren't cutting it anymore.

Anyway, and a frustrating morning it is up and running again and the new panel looks pretty good. You can see to the left of the outboard stack that the panels are all dark. Those are the scratch-built panels that still need to be replaced.

Thanks for the switch caps Gwyn!

Mike,
My 727 OH as well as yours also should pull about 6.5 to 7amps total MAX when all the panels are on.

Where did you find that info? That's very useful to know.

I'm also running the control stand lightplates and the forward radio rack lightplates from this same supply (and switch).

I found some pieces and parts from Mouser that I'll be ordering shortly. I'm getting tired of replacing this switch.

That looks really great....

You know what's funny? I have exactly the same lamps in my Super Connie cockpit. The only difference is that my caps are opaque and yours are clear. And I think they are still produced.

One question... do you have 4 blue caps you don't need? I could use them on my F/E panel.

No, but I have one though I'd trade to you for a red cap for my parking brake lamp on my quadrant.

The blue cap is from my pax address panel. I can stick an amber one in there.

Let me know.

Korry has been making that lamp for decades. It's in about 6 bazillion aircraft.
