    A new forumite whose first post resurrects an 11 years old thread, only to give a wrong advice.
    That's remarkable to say the least... :rolleyes:
    But welcome anyway! :)

    You can’t go from 32v to 12v without rewiring. Down to 24v is ok. The problem is that in many cases you will have old wiring and possible questionable connections which will make any issue worst

    Lighting is not a worry due to low wattage LEDs but I certainly wouldn’t run critical stuff like bilge pumps on 24v and old wiring.

    Ah, one of my thingies, I luv air starters. Ingersoll Rand makes most of them but there are others.
    One of my favorite boats was an old Huckins that on the bridge, you would hit a switch and the Speed Aire compressor would start charging a cast iron, 100 gallon bottle with 1" air hoses to the mains.
    In this time, you would slack some lines, check the weather, continue your personal chemical experimentation producing ammonia.
    Then, Hit the air heater and engage the air starter,,, wwrrrreeerrrreeerrrreeeaaa, rruummpphhaaa.
    Gad I luv the sound of air starters. Now one main is running, Finish that coffee and lite up the other,, wwrrrreeerrrreeerrrreeeaaa, rruummpphhaaa.
    We luv boats that make lots of good sounds and belch black smoke.

    Yep, Rowinco would start on over 10 year old fuel on her air starters.
    I mis that pig..

    Oh, Back on topic,, By the time you invest in an air system this power-full, You have purchased enough 8V batteries for the next 100 years..

    Do I have to explain K I S S ??

    LOLOLOLOL they remind me of being in a wheel and tire store...….but remind me of a Striker I ran with Schraeder Bellows air operated electronic controls...….they only put them on 14 boats before changing to a different system. They were 24 volt (on an all 12 volt boat), so 2 motorcycle batteries in engine room with their own battery charger, that plugged into a GFCI outlet, so needed a battery charger to keep that charged, generator to run the charger and air compressor, and then 1 of the 2 air compressors running in order for the solenoids (air) to work for the shift and throttle. Lose any one of those and you just lost control.

    Update
    I have an electric 5 hp air compressor already on board. With a 30 gallon bottle.
    Also a truck air compressor direct driven on the back of my port main engine.
    We have air driven windshield wipers (AirPush) and a loud (Very) horn system.
    Just in the Rand starters, an extra air bottle, electric air valves, 1" + air connects and hoses, I will have already been past my Viking funeral before any payback.

    The larger WM stores will have 24V stuff on the shelf. The super stores may have some 32V stuff but it is usually ordered in.

    And a lot of non but good WM stores will have 24 volt items. Basically just about any 1988 or newer 45'+ yacht will all use 24 volt equipment.

    Agreed. Completing the transformation now on the engines from 32 (36) to 24. Replacing the cables. old ones are compromised and brittle, albeit still functioning. But they've worn out their usefulness over 40 years. Batteries have been relocated close to the mains as to minimize the cable runs as well. Splitting off the extra battery from each 36v pack to create a secondary house 24v. I spread the pain over a few years, and the process worked well. Glad it's finished.
