Help with FlyLED install

We are installing the FlyLED works onto my neighbors RV8 and are having trouble getting them to flash.
When we hook up the 9V battery like the instructions say, we get the flashing LEDs on the board. When we hook it up to aircraft power (12v) we get nothing. We have checked that we are getting power and have a good ground to the board.
We've tried with the wing and tail strobes connected and disconnected. We've traced our wiring out to the wings and tail, and have good continuity. We have triple checked the wiring into the control circuitboard.
We've run out of ideas. We're stumped by the fact that it seems to work with the 9v battery, but not the aircraft power.

We appreciate any insight or help.
Cheers,
Chris
 
How are you checking for power, with a digital meter? If so, try using a
12 volt test light instead, the type that does NOT have an internal battery.
 
Solved

They sent great info for us to troubleshoot. It turned out to be the old power line that was running the Whelan. It checked good 12v, but wouldn't power up the FLyLED. New wire fixed everything.
