I went to fuse box and checked the two 30a fuses located at top of what i will call the DC distribution panel. no issues. the negative from battery connects to top left terminal on panel. the positive comes in and leaves on white wire from battery on top right. Right beside it is a red wire which the panel says is the positive from converter. when i put meter on the white and black terminals, there was not power. Could this be a bad converter??DC inline fuse blows when battery power turned onI have a 2008 Fun Finder with a DC power issue. I just replaced the battery because the dealer put a bad battery on the trailer. Anyway, when I go to turn on the DC power to trailer, it blows the inline 30 amp fuse. it is located on the negative side of battery. I have a plunger type switch to turn on/off DC power to cabin. the shore power works fine, but not sure it is recharging the battery. Any ideas on where to start will be appreicated. If you need more info to diagnose the problem, let me know.
