Battery boxes

[daveinaz]

Guess it’s my day for stupid guestions, but here goes.

I went to put on the two battery boxes and hook them up to the venting. (They weren’t attached when I got the trailer.) But when I went to put the tops on, I found that they don’t exactly fit what with all the cables on them. Are these just made for when the batteries aren’t connected? Because I don’t see how to get the top of the battery boxes secured to the bottom when the cable prevent the top from mating up with the bottom. If you have any pics that’d be fantastic.

Thanks.
