One more point:

I have never seen a grounding strap welded to the frame. I would be
suspicious of the person/business who did that. By welding the strap,
the heat may have ruined the strap or some other grounding part. Check
all your grounding wires/frame and etc.

The majority of problems with 12 volt systems are due to a bad ground
somewhere.

Thanks, again, Hank, and the rest of you who took time to answer -

I should have said 'soldered' to the frame, if that makes any
difference at all. So, that could be the problem, then. The
grounding wire is just that, a coated wire with a washer-type end; the
wire is just long enough to reach the frame (the battery is mounted in
front of the trailer - the previous owners, as I said, didn't use a
battery and the owners before that appear to have stowed one under the
dining-table bench, next to the water tank, because that's where all
the wiring ended before we took it to the shop).

After discovering that the wire had popped free, we screwed the wire
to the frame through a hole that was already there. Now that I think
about it, we probably should have scraped all the paint off from
around the hole so there would be a good metal-to-metal contact, but
you're saying the battery shouldn't be grounded to the frame at all?
Where should the ground be attached?

I'm getting a battery charger today and will see if the battery will
take and hold the charge. We're taking the trailer out this weekend
and are prepared to use lanterns because this doesn't appear to be
something we can solve by then.

Looks like I'll have to take the trailer back to the shop and ask more
questions. The harness on the tow vehicle, a 2002 Tundra, was also
installed by the shop. No problems with the vehicle electrical, so
far.

I do have a book about 12V systems, but it deals primarily with much
more complex setups that include multi-circuit converters, display
panels, inverters and multiple batteries, so it hasn't been of much
use for basic Vintage-Trailers-for Dummies information.

I'm glad you folks are out there, taking time for folks like me.
