General info needed
« on: July 29, 2017, 11:34:17 AM »
Hello everyone
  COB here
Listen we just purchased a  1993 Ledger pull behind.  Right now it is parked where i cannot get 110 to it. Put a brand new battery in it which sits on the tongue and have no power to anything. Wanting to get the slider out to check for leaks etc. Have checked all breakers that i can find but still nothing. Many years ago we had an RV and we had to flip a switch to go from 110 to generator.  Thought maybe this might have a switch that goes from 110 to DC but cannot find anything on or in this thing. Tried searching on-line for an operators manual but no such luck.
 
 Any information will be much appreciated.

  Thanks
    COB

Any chance it has a disconnect switch that turns off all the 12 volt. They are usually beside the entrance door. Lots of people call them salesman switches because salesman like to have all the lights on for sales viewing. They can easily shut off all the lights and everything 12 volt with one switch. Just a thought. If you have a tester, start tracing wires and looking for power.

No, there is no "110 to DC" switch. Nothing that runs on 110 uses DC and vice versa. Your RV gets its 12v DC from either the battery or the onboard converter/charger, which produced DC from  110 AC shore power.

You said "no power to anything". Does that include interior lighting? Sorry if that seems too obvious, but I wanted to be clear on the power status.

In all probability the battery hook-up in incorrect. In a 93 vintage trailer, there would typically be multiple wires to the battery, two for charging, two for 12v power, and probably another one or two for emergency trailer brakes. Tell us more about what you have, and a photo of the battery wiring would be good too.

Sometimes there is a DC switch inside that is used to turn off battery power for storage, but it's not very common on older trailers.

Welcome!!!

Your slide operates on 12Volts (batteries) so you will have to check fuses, not breakers. Breakers only protect 120V (plugged in) power. You might want to check just under the trailer where the A frame goes under the trailer itself. There is often a junction box just before the battery wiring goes into the trailer body and there MAY be a large re-settable breaker for 12V there.

 I have never heard of a switching arrangement  for 110V to 12V like you described. The wiring is in no way compatible!! You might also check for a battery disconnect switch somewhere on the trailer. These are sometimes used to prevent battery discharge during storage.

Welcome to the Forum.

Your RV basically has two (almost) independent power systems.   The 12 VDC system is battery powered and powers almost all lights, slides, TV and radio, power tongue jack, appliance control circuits and TT break away brakes.

120 VAC comes from generator or shore power (plugged into power).  This powers the normal AC stuff like microwave, hair drier, coffee pot and lights plugged into AC receptacles.

AC is supplied from generators or shore power and goes through CIRCUIT BREAKERS, and often have a CONVERTER to change 120 VAC to 12 VDC to charge the batteries.

DC power goes through automotive type FUSES and is provided from the converter and many tow vehicles while towing to help charge the batteries.  Some campers have an INVERTER to invert 12 VDC to 120 VAC to run low power items.

Appliances all require 12 VDC for their control circuits, in addition to propane or 120 VAC to run the appliance.  This includes water heater, refrigerator, furnace and A/C.

Hope the information helps.

It's not a dumb question if you do not know the answer.

Thanks. I thought maybe there was another bubblehead here.
