I tested the DC power source. It puts out just over 13.8 volts on "converter", none when switched to "battery".
So, all this time I thought it was a chargerโฆ
I think I will need to wire it to put charge into battery.
It has two 12+ outs and one ground.
One 12+ goes to "lights"
The other 12+ goes to (really comes from) "battery" +.
When switched to converter the lights wire has power, but none on battery. When switch to battery the lights goes dead and if I had a battery there would be battery voltage from the battery wire and on the lights wire from the battery presumably.
When I switch to "battery" the "lights" and "battery" 12+ wire get connected, when I switch to "converter" there is no connection between batt and converter wires.
So, both the battery and the converter feed into the "lights" output to power the camper, and there is a select switch to choose which one, but I can't tell that any power goes back to the battery.
So< i should be able to add a switch to run power to the battery from the "lights" output 12+ wire and give battery 13.8v charge.
So, anyway, I think 13.8 is good charge voltage given the solar is the primary power source, so I will keep this power source.
And, likely I had a birdsnest of wiring and the "lights" got connected in the nest to a 12+ from the battery which would have fed back into the battery to do some charging, so I guess it did work. This is off my first camper, and I have refined my skills quite a bit since then.
Also, In 20 years I have stayed at one campground and that was because we were at a specific event and was the only place to park, and it was literally 19 yrs ago. I'm sure not eyeing those restrictive retirement campgrounds, but thanks for heads upโฆ
I always have triangles, never used them, but have changed flats a few times on the interstate. Don't park on the left to change a left tire, park on the right with your rear end out in traffic so you get hit, at least cops won't give you a ticket for having a flat.
btw, this is something everyone needs to know about:
