No DC power to trailer, batteries good
Our trailer has power when plugged into AC but no power with the batteries. Batteries are almost new and ready 12.7 - fully charged when checked with a meter. I made sure the battery cut off switch ...

Our problem with the DC happened after returning from a 8 week trip. Batteries worked fine for 4 weeks and they test well.
I have been unable to find an inline fuse or breaker to date.
Thanks to all for your help! When it quits raining here, I can continue the search for the issue.
OK then 'reverse polarity' fuses on converter are OK
With a voltmeter check voltage on battery side and on trailer side of 'disconnect switch'....is it really working when you turn it ON?
And follow positive cable from battery to where it goes into trailer.....the in-line fuse (or Circuit breaker) are typically under tongue of trailer (It's like a scavenger hunt)
