Hep with Wire Hookups to Coach Battery

[JD51]

Embarrassing but I can't find pic we took when we disconnected the coach battery. We have a 2017 Jayco Greyhawk class C. There are 3 cables tapped together and then one single wire. All are black. Which set goes to postive? Help?

The end with 3 (mine has 4 but two are mated together) goes on positive.

The single goes to negative.

We have 4 also with two of the four hooked together. That one(2 wires) has yellow tape, one has white tape the other just black. The single wire is has a veregated type wrap and a copper colored end. So are you saying the 4 go to positive?

What battery messes. I've never understood why folks have such questions about getting battery cables connected to the right battery pole. However, looking at those images above, it's no wonder.

WHY doesn't Jayco color code the cables? That seems to be an obvious need that even an RV engineer could understand. A little heat shrink color tubing could solve this problem.

Yes, what you said is correct. If in doubt follow the negative lead (the single) under the motorhome and see where it goes. Should terminate to a ground somewhere close by. You will need to crawl under to verify this.

Thanks.

I have 2012 31FS. Your picture and this thread just solved one of my issues so thanks. The single black wire with the white tape on it is the ground. Using a multimeter, none of the cables including the taped one indicated a good ground. Guess I will have to trace that mess to find where it is or should be grounded to the frame.
