Shore Power??

Hey guys, new to RV'ing and have a quick question. I have done some research regarding this, but most of the things I'm finding pertain to different amperage and which type of adapters to use.

I have a Lance Lite 815 which uses a 30 amp connector. With the battery disconnected, I attached the truck campers power connector to the 30/15 amp adaptor and plugged it into a standard household outlet. Went to turn on a light to check for power, and nothing. Then I plugged the power cord and adapter into my Yamaha 2000 watt generator, and once again, nothing.

Then I connected the battery to check to make sure I didn't blow any fuses, and everything worked fine.

I need some help on understanding how shore power works. Does the battery need to be connected for shore power to work? My thoughts tell me that the power received from an outlet or generator would be used to charge the battery constantly? Orshould the shore power work indecently from the battery? Thanks for the help in advance

  • What is the battery voltage when plugged in? Looking for about 13.6 volts. Otherwise your converter might be off, stopped working or a fuse/switch is open.

    Generally the converter should supply 12v power with or without a battery.
  • Many converters will provide 12 volts DC without a battery.
    You should have 120 volt outlets. Use a proven good device such as a 120 volt drill or light to insure you have 120 volts to the rig.
    Locate your 120 volt AC panelinsure all breakers are turned on. I would suggest turning them all off, applying light pressure toward offthen turn them on one at a time.
    Locate the 12 volt DC panel. Many rigshave them behind a small plate held on by thumb screw adjacent to the 120 volt circuit breakers. Test using a 12 volt test lamp or volt meter to verify.
    Locate your converter and post make and model.
    You didn't say what year. This sheet shows rig has 45 amp converter.
    Lance specs and other info.
  • Yes lights pump etc are 12v and need battery connected. When on shore power converter charges battery but doesn't (shouldn't) supply 12v directly. Any AC receptacles/appliances should work without battery connected. IF battery disconnected ensure cables cant short- they will be hot from converter if on shore power.
