battery & 7way Junction box

zorro · July 2016

I’m trying to track down a possible electrical short in our TAB. Does anyone know how to open the junction box that’s under the trailer? This is a little black box that the power lead from the battery goes into & the 7 way cable. I’ve remove the two 10mm screws, but the box will not open. Is there a trick to it? Any help would be appreciated. I need to test the red power lead to see if there is current too & from the box.

Just need to pry the cap off. I used a small screwdriver. A rock knocked a hole in mine so took it off to repair. There's pics in this thread...

Thank you for your help and all the other people on the form. Now I've tracked down one problem. I am not getting any power from the battery to the junction box. The installation around the 30 amp fuse connection is cracked and maybe damaged.

Hopefully that's it - Sounds like a somewhat easy thing to fix.
