Nice idea but towboaters are not that pristine. I wish!

An internal circuit breaker reset? A temperature sensor cooled enough to allow normal operation?

Sorry to hear about your troubles. Just a reminder that fuses are notoriously "slow" in electrical terms. With advanced electronics the damage can be done well before any fuses blow. Breakers are better, just. One of the reasons the more capable surge protection schemes rely on a combination of things like MOVs and Diodes.

Another thought {rare} for the return of the radio is that caps that got overcharged coming back down normal operating range?

In any case, good luck with the tech and let us know what they find.

I'd expect overloaded caps to blow. A well made marine VHF rig may well have a thermal protection circuit that reset itself.

This is too weird. Maybe the lightning strike damaged one of the ship's cable assemblies? If you're dealing with a wonky junction or connector...
