120 is fine, cables are on the right terminals.
i thinking the problem is the brakes , i tried it with the breakaway pulled out, blew fuse, put it back in, blew fuse.
ok my thinking is
since i have all fuses out of the panel their's nothing connected on the trailer. are trailer emergency breaks hard wired so to speak, in that their is no fuse, i mean i trying to find what could be blowing it.
guess my next step is to pull the converter , disconnect the 12 volt fuse panel and see if is still blows fuses . i have all of them out and wondering if a short is in the fuse block on the panel itself.
gasping at anything to try. their are no signs of mice or anything that chewed on any wires.
