if u know this with
the battery disconnected, it sounds like the battery or the charging section. sense the converter doesn't throw the breaker until the battery it there, try a different battery and make sure of the polarity.
the bat and the converter both supply the 12v. if the converter is not working and ur plugged into shore power, the 12v still works. if u dissconnect the battery and plug into shore power and the 12v still works, ur converter section is working.
on my older trailer (84), the converter was switched in and out when u plug and unplug from shore power. the new ones are on with the battery (truned out that way on my 2002 is anyway). the switch on my converter turns the converter off...i don't think any part of it is active with the switch off. urs may not be turning off, that is why i ask abt the battery being disconnected and the shore power on. that is an easy way to prove the converter section is or is not working.
