Electrical question

I removed the coach batteries for the winter. I want to do some work inside the coach, my question is should I put the coach batteries back in before starting  to work inside or can I just plug in. If I just plug in do I have to take any precautions with the loose disconnected cables in the coach battery compartment? Thanks.

It is fine to plug into a 110V source to power up the interior 12V lighting without batteries present.  With the inverter running, you must insulate the red/+ terminal (s) well.  It is good practice to let them hang down below the rig.  Even better in the outdoors is to disconnect the red wire(s) from the fuse in the back of the battery compartment.  Then you are assured you are safe.

Here is the back of my battery compartment with fuses in-view.  I have just one hot/red/+ wire, the one coming toward the camera.  Disconnect it at the fuse block and it would be most safe.

Makes sense, many thanks!

Another think you could do is rape the red lead with Scott 33 tape about 3 laps over the battery connector and it would be save to run the 110 vac shore power.
