Howdy; new guy. Would LOVE to have an electrical diagram

[dcolman24]

Howdy. New (to me) 2011 model R21EC owner. I am a live-aboard in San Diego and use the Ranger for transportation and recreation. Toying with the idea of a water taxi biz. I am tickled-pink with this thing. It's my favorite toy I've ever had and second place isn't close. The Ranger seems like a quality build to me, but the documentation is very disappointing. Seems like Ranger went the same way as the RV manufacturers... putting all the responsibilities on the installed equipment manufacturers. Anyways before I fall into another pet-peeve rabbit-hole, I would love to have an electrical schematic of the R21. I thought it would be easy to find but not so. Can anybody point me in the right direction?

Good luck, Chuck. I have a 2012 R27. The electrical schematic in the owner’s manual for it has significant errors and omissions. Examples: According to the schematic, the windlass doesn’t exist. The house batteries are not shown wired in parallel.

If you find a schematic, take it only as a suggestion of how it might be wired.

Second what CaspersCruiser said about the accuracy of the factory wiring diagram for your specific boat. Prior owners may have made changes. The factory installer might have been creative.
Also, things may not physically be where they indicated to be located. On our former 2009 R-25 Classic, I had a main DC resettable fuse tucked away in the bilge on my boat - about 3 ft away from where it was shown to be on the diagram.
Good luck!

I’m in the process of drawing up an as-built for our new 2023 R27 LE. Focusing mainly on the power side as I really want to fully understand the AC and DC charging and distribution systems. Gonna take a while to trace the wiring. But a great way to get to know the ship from stem to stern which will be very helpful as things will undoubtedly need some trouble shooting in the future.

The very nice thing is that the factory has done a beautiful job in fabrication. All neatly labeled and professionally wired. Extremely well laid out, so that should make it a lot easier. I really didn’t expect a full set of drawings… boat building seems to be very much a bespoke art.

The below is what I have after tracing wires on both a NW edition and an LE edition.

That is pretty awesome Martin. Thanks!

Looking at your drawing I’m betting that’s 99%. You must have spent a lot of time on your belly head down in the lazarettes. Lol. Only thing I see different so far are that I have 2 - 280Ah LiFeP04 instead of the 6 100s. Are you ok with me using this as my basis?

Thanks again.

Absolutely!

Martin, do you have a diagram of the network of your boat available?

I like having only 1 battery for my house bank. Less cables, it's cleaner in my opinion. It's 320amp-hours. Lithionics also makes a 630amp-hour single battery that would also work in this setup without any modifications needed. The 320ah and 630ah do not support being connected in parallel or series with another battery. They must be installed stand-alone.

The J1939 (engine) network and the Nema 2000 network are documented here:

For Internet networking, it's all wireless. 5g/LTE router with 1 modem and 2 SIM cards for diversity. The WAN port goes to Starlink. I'll have a drawing for this shortly. It's much simpler than electrical and N2k. 🙂
