I should have thought about Yandina's lifetime warranty and that they made the West Marine units from years ago.

Yandina's current combiners switch at 13.3 volts or greater. Not to be picky but most voltmeters aren't accurate enough to tell the difference between 13.3 and 13.5 volts, so there is a possibility that your shore power charger is set to a low enough float voltage so that it will never let the combiner switch on.

Is it an adjustable charger and can you increase the float voltage? Another test is to start the propulsion engine and see if its alternator won't kick the voltage up high enough to switch the combiner.

But if Yandina fixes it, all the better.
