I just bought a 2020 heartland 305 toy hauler. The problem is nothing works on 12 volt. I tested the battery and it's good. I turned the battery disconnect key both ways and nothing either way works. I was wondering if there is another switch somewhere? Also looked at the fuses and they're all good

Try plugging it in if the 12-volt stuff starts working then you know the charger converter is working and your battery disconnect is not hooking up to the battery you need to test power on both sides of the switches or see if you have any power at the 12-volt fuses with a test light maybe the disconnect switch ...the manual one... broke inside and there could also be another electrical battery disconnect switch from the inside of the coach either way most of them are wired so if you are plugged into household current the 12-volt should work off the converter even without a battery unless the main power for the fuse panel is fed from the batteries theirselves also you can test a 12-volt ground Circuit by applying your test light to a clean part of the chassis and putting the positive on the coach batteries and see if you have a light if you don't you have a bad ground
