Cobra Passport battery wiring

We're looking to see diagram of the two batteries under the hood. Took the one out for replacement and forgot how it went. It's the battery that runs everything on the inside of the home. Hope you can help.

  • Too late now but I take numerous pictures as I put something together or pull anything apart. 

     

  • Well, either the OP forgot they posted a question, figured it out or possibly sitting,  staring at cooked electrical system becuase + can’t = -.  

  • + wires go to + side, the rest go to - side. If you guess and don’t check you’ll know immediately!

    PS, the chances of someone here having that rv are almost 0 and the chances it’s got all the same wires after 40 years is even less. 
    if you removed the wires from the battery and suffered short term memory loss and/or didn’t label, just check which ones are continuous to ground and the rest are +. 
    If you don’t understand that, call a mechanic or make sure your comprehensive policy is paid up!

  • maybe add a couple good picture of what your dealing with and even thoes that don't own that spicific rv might be able to help you
