Whenever strange electrical things happen AFTER installation of new battery one has to ask
"Are you sure you connected new battery correctly?"
Battery cables are not standard colors like automotive.
Black is usually POSITIVE and white IS NEGATIVE (but then you could have RED and GREEN)
Point is.......follow battery NEG cable to frame ground
Usually the converter has 'reverse polarity' fuses that blow when battery is connected backwards. They are large (30A/40A) fuses on converter ....can be on front/side/back of case
If you unplug AC shore power do you have any 12V DC power? If not reverse polarity fuses or a MAIN battery fuse on POS cable to converter blown
Also your converter should have a DC output of 13.2V DC minimum when connected to 120V AC shore power (without battery cables connected
What RV do you have.......year/mfg/model?
