A new issue arose on my recently purchased RV, when my battery went dead. I thought maybe I left something on but when I put an ohm meter from trailer frame ground to positive terminal I found no resistance (direct short) by a process of elimination of removing fuses I determined the short is coming from the component side of the fuse which powers all the lights in the cabin and the propane detector and God knows what else. I really don't know where to begin nor do I understand why the fuse doesn't blow. I know when I leave it on A/C power all appears normal. Guess I need wiring schematics and a better knowledge of inverter technology. One last thing it , when a/c connected the battery is receiving 13.3 volts so I believe the investor is ok. I know this isn't good with car mechanics and maybe it isn't blowing the fuse because it's a leak and not a direct short although it ohms out at less than one ohm. My big concern right now is safety no breakers are popping nor any blown fuses ever but showing any kind short from power to ground concerns me greatly when A/C current is involved. Any assistance is appreciated
