overview of parts and what they are for

[crus]

I just bought a 1993 maxum 2300crs and it my first boat ever and the previous owner didnt explain to me clearly what what is and what it is for. he just printed a manual for another series but it doesnt really have this info.

1)
so on this picture is the shorepower panel:


is it correct to say that not connected to shorepower these switches are virtually meaningles.. whatever position they are in?
Or should they all be to off position when not connected to shorepower?

also, what does 'receptables' and 'range' mean?


2)
this is another electrical switchboard and i have no clue what it does/ what its for:



3)
in the engine bay is a big red power switch that says:
OFF - 1 - ALL - 2

obviously OFF means all power disabled and ALL: all circuits on, but i tried the 1 and 2 position and didnt notice anything different from ALL.

what is 1 and 2 postion for?


4)
What is this tank for?



5)
how does the waste cap work?
do you just open it up and insert a special hose to drain it?
how do you know if it is full?


6) how do you know if the clear watertank is full or empty?


I know, a lot of questions but very grateful if someone can help me out understanding these things which are probably completely basic knowledge to most of you but not for a novice like me.

1. Yes that's the shore power breaker panel. Just leave the breaks in the off position if not in use.

2. That was not factory installed. I would have to google it to fully understand what it is for but seems to be power management for shore power devices.

3. Battery switch; 1 is battery one and 2 is battery 2. It's used to isolate the two batteries so if you run one down while anchored you can switch to the other to start the engine.

4. Holding tank for head waste

5. Local marina should have a pump out station that uses vacuum to suck the waste tank dry. Adapter threads in then a hose connects to it.

6. Freshwater tank looks similar to the holding tank, only way is to fill it until water comes out the fill or just look at the tank and you will see the water line. There are aftermarket level indicators that can be installed. RV stores sell them cheaper than marine stores.

thx!

one more thing:
what does 'receptables' and 'range' switches mean on the panel?

[jparsons121]

They are the breakers for the household 110/120 outlets (recepticals).
Range is the breaker for the electric for the stovetop.

All of the breakers only work on shore power. Once plugged in, the main breaker sends power to the individual breakers. The individual breakers send power to each dedicated circuit. It's just like a breaker panel in a residence.

Range = Stove top
Receptacles = Electrical wall outlets

Also, I would assume that my battery charger is on whenever I'm plugged into shorepower (Make sure to turn the battery charger OFF before starting the engine). I, personally, leave the hotwater heater off whenever I'm away from the boat for extended periods of time.

What they said.

#3 - if wired correctly you should start and cruise on position 1 and switch to position 2 when on the hook and not plugged in to shore power.

Battery #1 should be a starting battery
Battery #2 should be a marine deep cycle battery to supply power to the house.

Your Refrigerator should run on both shore power and the battery so be careful not to kill the house battery with the fridge.
