Continuing my Oday 192 survey... bear with me!

[EnamrdSalr21]

Hi all! Thanks for the comments on my last posts. Wondering if you might be able to help again as I try and sort the electrical for my Oday 192. I currently have the circuit breaker, the voltage meter, cigarette lighter (as you can tell I'm not an electrician by any means), and a rats nest of old wiring.
No cabin light, no fan, no battery. I do have an anchor light, bow light, and transom light. I would love to have some type of diagram to help me get things in the right place. Anyone have something like this?

Read through these introductory articles for a start:

There are plenty of books on Boats wiring out there and I would recommend "Sailboat Electrics Simplified" by Don Casey.

Guess I should get to reading!

As someone who bought a boat that was wired with lamp cord and masking tape ,perhaps my experiance will help .
I was able to find a schematic for my boat when it was new . So much had happened by subsequent owners that none of the original
wires actually did their original job .
I ended up pulling as much of the orignal wiring as I could and started from scratch .
Some of the factory wiring ran between the ceiling and the deck itself ..
It might sound like a lot more work up front.
I did this for two reasons . The first being I knew exactly which wires did what and that they were correct .
All circuits were drawn out ahead of time and fused correctly .
Second ,our boat was made in 1981 . Since then we sailors have added a great deal more electronics . I wanted to leave room for charging circuits , dual batteries , solar panels ,auto pilots and chartplotters. Most of these are almost considered mandatory ,by some .
I also chose to switch to LEDs lights in an effort to reduce the amps used .
I hope this helps

Yes this helps! It’s exactly my plan, actually. The wiring looked so bad I didn’t really trust any of it. I plan to give this thing a fresh start when it comes to electronics. Where did you locate the schematic? I haven’t had luck doing so for my boat yet…

I'm pretty sure it was here on this forum ,under boat info . The drawing was done by hand and not very encouraging

Idon't believe the 192 was sold with electronics. That would be an owner installed option. The Mariner was the same. Today, I think the Mariners produced by Stuart Marine may be available with electronics, but I am not aware of the 192 having that option from the manufacturer.

I will add to the previous posts by also stating that wire does corrode over time, and likewise the insulator that surrounds it will degrade. I also found some non-tinned wire in my 1985 O'day. Therefore, the more old wire you can remove the better IMHO.

I would also suggest you pick up a copy of "The 12 Volt Bible For Boats" originally written by Miner Brotherton and updated in the early 2000s by Ed Sherman. While not the most comprehensive, it nevertheless is very good at explaining the basics of vessel wiring.

I've looked at SBD.com at the 192 and it strikes me that the wiring should be pretty simple. I don't know what systems the OP would like to have but handhelds, battery operated lights and bluetooth speakers would probably work as well as a hard wired system. If the boat is going to be trailered I would avoid mast head instruments and lights. Raising and lowering the mast frequently may be detrimental to whatever is up there. I have a handheld VHF which has GPS so I get position, SOG, course, and an AM/FM radio, And it can go home with me.
If the OP enjoys projects then have at it. But I think portables should get a look.
