Fridge and watermaker on 27' mono?

Yes you can. Set the float voltage to the same as the bulk/absorption voltage - 14.4 volts for example.

That is what I do to my Outback 80 to prevent it from going to float prematurely.
Maine Sail in one of his posts recommended it.
Of course don’t do this if you Boat is unoccupied on a mooring, then with little to no energy consumption, you could overcharge and damage your bank, but when cruising and using energy, it’s much less likely.

But alternators in general are a mystery to me. Any discussion of them at all would surely be helpful. I DO WANT to maximize whatever charging potential is to be had from the engine.

..... and I was planning to do that. But I don't fully understand regulators, so I need to do some reading. I seem to recall MaineSail wrote a good long article about regulators, I'll have to look it up this evening.

Something seems to be wrong with the link.

Simple is good! We run 2-110 amp alternators off of one engine with 2 external, 3 stage voltage regulators. One alternator is for the house bank and one is for the start circuit/engine gauges only. No interconnecting switches.

We do carry a spare alternator, regulator and jumper cables. Have never needed the jumper cables in 16000 plus miles. KISS
