Battery hooked up backwards

Anyone familiar with a travel supreme express 33rl. I hooked the batteries up backwards so now i have no 12v power through the trailer. I can't find an inline fuse or converter anywhere. Does anyone have any ideas, thank you.

The converter may be part of the circuit breaker panel. There should be a pair of 40 or 50 amp ATS fuses that blow from reverse polarity. Look for 2 fuses the same color.

AS above.......

Reverse Polarity fuses blow when batteries connected backwards to protect the converter

Reverse Polarity fuses could be part of the DC Fuse Panel or on the converter if converter is stand-alone style vs lower part of AC Power Center

Stand-alone style could be behind the AC Power Center


What year is your RV??

X2 on Twinboat,s post. Circuit breakers, fuses, converter, charger all in one box is common. Post make and model of combined box if you have one. Post a picture if possible.
