Make sure the battery is installed correctly... Find the word NEG or SYMBOL '-' stamped on the battery case and make sure this is the TERMINAL that goes directly to FRAME GROUND near the battery install area.... RV Colors are normally BLACK for Positive and White for Ground. But since the AUTOMOTIVE BATTERIES are RED for Positive and BLACK for Ground it is real easy to get the battery hooked up in REVERSE order on the RV which will immediately blow the REVERSE POLARITY fuses and perphas another large capacity fuse or CB near the battery terminals...
Having a MULTIMETER handy at all times makes it easy to check out things like this...
