Wingtip Strobe Wiring

[bob865]

Hey Everyone.  The uAvionix SkyBeacon finally has its certification and is on sale!  Planning on picking one up at Oshkosh.  Planning for the install I'm trying to figure out how the strobes on the wingtips are wired up.  I went through the prints that were posted in the download section and I don't see wingtip strobes in any of the prints.  I have a '75 E model.  In the cockpit I have two separate switches, one for position lights and one for the strobes. 

Anyway, the strobes must have a high voltage power supply somewhere.  So my question is, where is it?   And are there separate power supplies for each wingtip or is it one for both wingtips?

Look for an access panel about 2 feet in from the wing tip. It will have 4 screw heads in it to hold the strobe power supply.

For more details regarding Uavionix...

Some of the questions are answered and others arose there too....

Best regards,

Thanks.  One on each wing?  Or is there only one for both stobes?

If there isn’t one in each wing then there is a common power supply in the tail cone.

If it is a Whelen, it should have one in each wing. Cannot say what is used in Hoskins systems.

Hoskins also has one in each wingtip.

They started putting the power supplies in the wings because when you put the power supply in the fuselage you are running high voltage wires next to the fuel tanks. A chafed wire could make an arc and ignite vapors from a leaky fuel tank.

Good to know.  My concern is there would be only one power supply and disconnecting only one strobe would make both inop.  As long as I have a power supply in both wing tips, I'm all good.  Going to look at the plane after work today and see if I can locate the panel where the power supplies live.
