This is difficult to diagnose without
measurements.
All AEC products have lifetime warranty.
If you would priority mail your module
to me, I'll check it on the acceptance test
fixture, evaluate its performance and
return it to you with any necessary
repairs in place.
We don't often get a chance to evaluate
fielded products. I'd be pleased to assist
by checking off at least one box in the
troubleshooting process.

Thanks Bob, I'll see if I can measure voltage at the incoming pin as to
isolate the wiring from the device. If the voltage there is on par with the
Dynon indication, I'll send the unit over.
