Bryan,
Go to whelen.com and view the Installation and service manual notes.
Check power and ground to the unit.
Ohm out from the unit to the wings.
Remove unit and bench test.
If a Whelen unit (especially the older ones) has set for a long while,
they need to be brought up to voltage slowly. I use a 9 volt drill
battery to charge it for 15-30 minutes if the plane has not been used in
a long time (12 months). Some of the units had a fuse inside the unit
that could be changed, but that was a long time ago. Newer units are
pretty full proof.
If the unit is getting power and not working, best to send it in. I
have repaired one in the shop at the customer support guys suggestion,
and it was a blown fuse. Unless you are familiar with the unit, do not
open it up and just poke around.
Whelen is great about a fast turn around on the box.

Subject: Europa-List: Strobe problem
My strobe has stopped working! The problem could be with the wiring,
the strobe, or the box circuit.
Before I start reaching for the box in the confined spaces at the rear
of the fuselage, I thought it would be worth while asking advice from
others who had the problem. Is there a sensible diagnostic procedure to
avoid wasting time?
Bryan
