Thanks for all of the advice/responses. The positive battery cable goes under the A-frame and immediately up, into the floor of the trailer. I traced it with a tracer and it is unbroken back to the power boards/center and converter. No inline fuse/junction/etc. Googled the manual for the WFCO 45 amp converter and viola! Found 2/30 amp fuses (specifically for reversed polarity) on the "back" of the unit. Access to the fuses was virtually impossible due to where/how it was mounted. Managed to dismount the unit enough to coax the fuses out. Visual and continuity tests indicated they are OK. Even cleaned the ground for the neg. battery cable. At this point I figure the (14 year old) converter is shot. Thanks to all who came to my aid. Wish it had resulted in a better (cheaper) outcome. Stay safe.

Example: DC Circuit Breaker
One should note that the breaker shown in photo IS a "self reseting" or "auto reseting" breaker (IE no reset button to push) and is typical breaker used by RV manufacturers.
HOWEVER, in order to get this breaker to auto reset, one MUST REMOVE BOTH POWER SOURCES (IE converter must be powered down AND the battery source must be disconnected from the circuit). Once all power has been removed from the circuit then and only then will the breaker reset.
Do that first before throwing parts at this.
Some misinformation above here.
What is the black button for in the image if it is an auto reset breaker?
Auto reset breakers are automatic reset, no need to power down anything.

Fuse will be on POS cable
On the a-frame and will be a small 2 stud box...reset is typically on side of the DC Circuit Breaker

Old-Biscuit: I agree. But, cant find anything like that. No 30 amp fuses on the DC Dist Fuse Panel; just 15s and 20s.
I need to find the in-line fuse/breaker somehow. Thanks for all your comments and insights.
Follow the battery cable (likely the negative) from the battery to where it goes under the trailer look for small (approx 1" x 1.5") circuit breaker (box). Should be 2-3 ft from the battery, it may or may not have a reset button.
