carringb: Wiring diagram shows a 40 amp fuse between the battery and converter but I can't find it. Believe me, I have looked and looked...
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.
Except -----
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
Example: DC Circuit Breaker

Example: Reverse Polarity fuses on DC Dist Fuse Panel----40A
