12 volt reading light replacement question

[Cindy and Ray's Grand Tour]

I need to replace a switchable LED reading light in the bedroom above the bed. It is on 12V battery I believe. My trailer has an on/off switch next to the battery. If I turn off the battery there, can I safely change out the light without a shock? Will my 120V appliances (air conditioner) continue to run while I work on the light? I should know but I am not very mechanical at all. I bought the replacement light.

The On/Off switch next to the batteries is for the inverter which powers you residential refer. It will have no effect on the 12V power system. You have three options to turn off the 12V power:

o - Turn off the Battery Disconnect switch in the Convenience Center. This kills all 12V power to most everything but definitely the bedroom light. Quick and easy

o - Find the 12V fuse in the distribution panel and pull the one which feeds the bedroom light. The Old Worlds Craftsmen have really bad penmanship so finding the right fuse may take a bit of trial and error.

O - Disconnect the battery in the front compartment. This will kill all 12V power in the rig.

Most likely the 1st and 3rd options will cause the A/C to quit as there is a 12V control board in there (AFAIK). The fuse is the sure way to disconnect power and ensure other devices still work.

To make it simple for a novice.
-disconnect from shore power.
-remove the negative battery cable going to the frame of the camper.
-change out your light fixture (you will need to pay attention to which wire is the + wire) (the wire that goes though the switch).

If you can determine which fuse serves that light, just pull the fuse. 12 volts is not going to shock you. But pulling the fuse will prevent sparks when you work on it.

Have you ever changed a bulb? Just unplug the shore power and change it.
