Don't batteries have polarity clearly marked on them?
Yes, but when they can't be seen due to dirt, the cables aren't marked and pictures weren't taken (everyone just know how they came off) then you're up the creek without a paddle. Plus there is no standard color scheme that RV's use. Some may have a plan but none will hold up production because they ran out of some color... :@
Now add to the mix by changing battery sizes, terminal types and locations, parallel to/from serial and we play the battery doesn't work game... :S
