Does anyone have an internal wiring diagram for the Whelen HDACF power supply? Mine has failed for the second time in six years. With a diagram, I might be able to fix it myself rather than send it back to Whelen.

Thanks, Tom RV-7A flying

It is usually the electrolytic capacitors. They are prone to fail with age. Especially if you do not run them for long periods of time.

Alton, thanks for the idea. I will try that.

Another question about Whelen. Does anyone have a current phone number for them? All the numbers on their website have been disconnected or don't work.
