Orion 500 Position/Strobe Light

[AZOutlaw]

Recently replaced the old Whelan tail strobe with the Orion 500.  There was no "Nav" 28v wire in the tail as the position lights are on the rear of the wingtip on the Ovation.  Has anyone found a location to connect that position light lead on the Orion to the Nav circuit?  Does the Nav wiring go through the bay with the batteries/oxygen like the strobe wiring does?  I have a bundle of zip tied wire in there but we didn't want to cut it all loose unless we knew the Nav Circuit was there.

Why do you need to connect up the nav light portion of the fixture if you have the whites in the wing tips?

There is no nav light circuit in the tailcone, just strobe power. I replaced my wing nav/strobes with the 650Es together with the 500, which freed up wiring to/from the old failed (removed from bulkhead) wing strobe power supply, which were then used for nav light power and strobe sync. (I kept the wing aft position lights as incandescent, allowing proper dimming of the GEAR DOWN annunciator light. Lots of aft position lighting now.)

It sounds like you still have the old wing lights. I don’t think it would be worth the effort to splice into the wing light wiring under the cabin and run tailcone wiring just for a redundant position light.

The Ovations are pretty refined after decades of Mooneys that came before them…

I found it odd that there wasn’t a tail position light…

but, with two wing tip tail lights… we kinda got a spare….

 

Mooney wiring diagrams are available in the MMs… available electronically…

Looking in the tail…

There aren’t that many wires going past the tail hinge… if you want to take a look.

 

Compared to the M20C…

There was one wire going back there…

It was the tail position light…

 

The VOR antenna wires looked completely different…

PP thoughts only, not a mechanic…

As I understand it, the wingtips have 4 wires, two strobe and two nav.  And you can repurpose one of the ground wires to be the sync wire.

For the tail, if you want it to be synched, so you need to run a wire.  And if you are going to run one, might as well run two and hook up the nav portion.  Now or later.

Whelen Orion units have 4 wires, 

Black - Ground

Orange - Nav

White - Sync

Yellow - Strobe

I may have W & Y switched.

On my installation, the original Mooney wiring was terminated with a 4 pin Molex connector. No new wires had to be run.

For the wings, that is what I thought it was.  But the tail only has 2 wires on those the rear position lights are in the wing tips.

Hi All, thanks for the feedback.  I realize I don't need the rear tail position light but I have it built in so why not turn it on.  I was really just asking if anyone knows if the Nav light wiring ran through this area where the strobe light power does.  We removed the old strobe power supply (where the X is) and connected the wiring for the 650 strobe/Navs.  The tail strobe had a power supply in the tail but only one 28v power line off the strobe switch.

There's a lot of bundled wire down below and just wondered if anyone had found a Nav circuit there.

I was short a wire and had to pull one to get synch and nav but its only in the tail.  There were enough wires to the wing tips and everything was connected basically where your yellow X is.

I answered your question already, earlier in this topic. I included some other relevant info so maybe you didn’t see it. The answer to your question above is yes. Someone knows.

I know that it does not, as I stated earlier.
