What did I do wrong? Working on my 6062 norcold trying to get it to cool better. Replaced 3amp and 5amp fuse in electrical box and shorted out 5amp fuse when replacing it . Put another new fuse in , put every the back together "nothing".,eyebrow don't come on , wont go to gas, nothing. In front of converterer/charger there is a board with 6 15amp fuses,cannot get a reading on any of them. Any ideas?
