Has anyone had problems with a uAvionix Tail Beacon on a Skymaster?

Have never had an issue with tail beacon other than the 1st received unit would always fail the tests. We thought wiring, ground, bad switch, interference from alternators, etc. Did a flight with everything off, radios, alternators, everything…Also rattled the wires like crazy and always had power. Ended up deciding the unit was defective. Uavionix was very helpful but doubted that the unit was the issue. They agreed to swap us out with a different unit and the problem was resolved on 1st test flight. Probably rare, but could save some time and troubleshooting for others if ever a similar problem.
