What are those solar prep wires
Hi,
I got a chance to open the "solar prep" box in Entegra coach Odyssey ( almost the same as Jayco redhawk) and there are 3 groups of wires there:
1, White & Black;
2, White & Black with red type;
3, Red and White;
Does anyone know what are they?
I know they must be 1 group wire from MC4 entry plate on roof, maybe another pair of wire to battery? What is the 3rd pair of wire for?
Thank you!
-Ky

Well, I don't have the latest Jayco schematic and they have changed their solar prep wiring several times in the last few years. So I suggest you test my guess by finding the wires and checking with an ohm meter to be sure its right. But, based on the schematic I do have, I'm guessing that the red and white pair go to the roof gland, the red taped pair go to the house battery (or a CB near it) and the black and white without tape go to the chassis battery.

Thank you so much dvspl! Will check with multimeter.

Report back to this forum and hope it will help anyone.
3 groups of wire
While + Black : Seems not connect to anything;
While + Black + red strip: Seems not connect to anything;
Red + White: Red marked with + and white marked with -; Put a 1.5v AA battery through roof solar prep and red / white measured as 1.612v so I think this is the connection to root solar prep box.

Wiring diagram attached. According to this schematic, the black/white pair go to the chassis battery. The red taped pair is for the house battery and the third pair leads to the roof. This is so you can use a SCC to charge both house and chassis batteries.

Thank you this is helpful.
What I did is connect 1.5v Duracell battery to a cable to MC4 connector on roof and measure voltage with Fluke multi meter.
Red + White measured as -1.6v, I think somehow it is b/c I switched pos/neg but that's good enough to know Red/White IS connected to roof solar receptacle.
When I measure White + Black, key is in and turned dash on but engine not started, house battery is also on, LED light in RV lighted. Voltage between White + Black is open, between White + Black with red strip is also open so they are not connected to any batteries, I believe someone in Jayco may forgot to connect them to battery.

I think you are to make the final connections when you hook up the solar. They just do you the courtesy of installing the wires to make it easier for you.

Thanks cpd1343! That make sense and I do recall I see two white cables left at house and chassis battery respectively.
Thanks again!

Did you install any solar yet? Trying to help a friend with his Redhawk 26B, and researching installs. From the diagram, it looks like 8AWG wire, so not going to handle much...

I have a 2021 Alante with a set of 'solar prep' wires that look like the ones described in the original post. Can you comment on how likely your attached wiring diagram is to apply to my Alante? Also, how did you get this? I'd love to get a full wiring diagram for my Alante.

Jayco has been very good at providing schematics or wiring diagrams upon request. Email them at motorizedservice@jayco.com and ask for what you want.

i have 2021 entegra vision 27a. solar prep. the wires to chassis and house batteries are attached as white to neg on both batteries. the positive wires are safely attached to a ground terminal coveredwith a red rubber cover. the hunt for this info took several hours reading posts and just plain luck

I got the schematics fairly quickly from Jayco and installed my Victron solar controller where they come out in that front storage bay. The wires to the batteries have to be connected but they've run the wire.
