I am new to RVs. I took my house batteries out over the winter, checked the fluid, kept them charged once a month. But I didn't take a picture of the cables.

I thought if I stuck to red and black and the post size, I couldn't get it wrong but now I am having a problem.

When all my cables were hooked up, I started the engine to move the RV and after about 30 seconds there was clicking and I shut off the RV.

I did some troubleshooting one cable at a time and I have it narrowed down to the one cable that causes the problem. Two pictures attached. But now I am unsure of myself and I don't want to stick it on black just because that is the other choice. It got dark and I won't be able to trace the cables under the RV until this weekend. Any help on what I am doing wrong or should be looking for?
