[Rhodes22-list] electrical wiring diagram

[Lowe, Rob]

Chris,
Hey, pretty good for an architect :) (sorry, I'm an engineer).

1.  This sounds correct.  Typically battery 1 is your "house" battery and battery 2 is your starter battery.  Your starter battery will receive it's charging current from your outboard.  It would make sense that your lift is connected to the same battery.

2.  Not sure about your solar panels, but I would assume they are connected to your starter battery.  Your most important battery is your starter battery so it would make sense that your solar panels are connected to the starter battery to keep it charged. 

3.  That is correct.  The switch controls which battery(s) is connected to the bus.

4.  You have the buses labeled correctly.  Anything with an in-line fuse will be connected to the positive bus.  You don't state which colored wires are connected to which bus, but wiring conventions say the common (negative) wire should be white.  The positive can be black,  red, or even another color.  The larger wires carry more current, I assume the largest ones go to your motor and other high current devices.

Do your batteries get charged while on shore power?  If so, your got a battery charger somewhere in your boat which is probably wired to your buses.  How about AC power while not connected to shore power?  If so, you've got an inverter somewhere coming off the buses to feed your AC circuits.

1. The outboard has a single set of wires that appear to go to a block with
pos and neg terminals to which the starter is also connected.  This block
appears to be connected direct to battery #2, my starter battery.  I think
the  battery #2 directly powers the starter and lift and also receives a
charge direct from the outboard alternator.

2. I beleive the two solar panels go direct to battery #2 but I am not sure.
If I am correct then battery #2 would always receive a trickle charge when
the sun is shining and battery #2 could also recieve a charge if the battery
switch is in the both position.

3. The battery switch seems to control how power is provided from battery #1
and or battery #2  to the power bus.

4. The power bus seems to provide power to the main panel, the macerator,
the water pump, the vhf radio.  I see two big white wires and three small
white wires, two big black wires and four small black wires, I don't
understad were all of these go and what they do.

5. The main distribution panel seems to have switches that control circuites
to each of the appliances, cabin lights, dc outlets etc....

With input and corrections I can post a more accurate set of diagrams for
fleet reference.
