Well I just discovered that the original, old fan in the front skylight is not working...This fan ordinarily comes on automatically when the skylight is cranked open, and I've had it open lately...so maybe that is the source of my power draw? Can a frozen-up or burnt-out fan still draw current?

I think the old fan might present something more along the line if a dead short, or the opposite.... totally open.

Your 70 mA decreasing to 10 mA is most likely the reverse current into the PD converter/charger when not on, the 70 mA is the current needed to first charge the capacitors in it. I don't think the 10 mA is from the converter/charger though, it should be essentially 0 once the capacitors are charged.

If your meter is not showing anything but a 10 mA discharge, I cannot imagine what could be drawing down the battery.

Yes, the fan could draw power and not run, that surely would do it, but you are not measuring any power draw other than the 10 mA.

I had a fluorescent light (12 volt) once which when turned on, would not light, but did draw full power! That was fun to find. But again, you are not measuring any draw from your battery.

I am baffled from afar... but would be close up too, with the numbers you mention. Something has to be doing it. A ghost who turns on lights so they won't be afraid of the dark maybe?

Well- This will be interesting to other '70's owners, especially: my original '72 front skylight fan is likely the culprit regarding my battery drain problem, but time will tell.
I took all the stuff down to get at the fan, and then cranked up the skylight which normally turns the fan on. Always has, until now: no sound, no movement of the blades. I took the fan out, since I don't want it up in there any longer anyway, and I noticed that the blades turned, but very stiffly and reluctantly. Aha! I then checked the wiring with a test light, and it was hot, so I knew that it was a fan problem. I also wondered why a fuse hadn't blown.? I then spun the blades several times to kind of get it moving again, and then touched the leads directly to my battery. The thing actually acted like it wanted to work- it moved 10 degrees or so, halted, jerkily moved again, and so forth. So- it had mostly seized up due to lack of use (or some other problem, I don't really care), and was sitting up there straining whenever I had the skylight cranked open during hot days. I had completely forgotten that there was an automatically-switched fan up there, and couldn't see the blades jerking a few degrees due to the yellowed light shroud...Well, if this wouldn't quickly drain a battery, I don't know what would!
But it gets more interesting with the fuse situation, and other '70's owners should think about this- There are only 3 things on circuit # 5 in a '72 Overlander International model: That dang fan; the hot lead for the original radio/stereo behind the sliding doors in the front end-cap; and the CAR BATTERY Connection, POSITIVE LEAD! All protected by a massive 40-amp fuse, which is I guess why the poor little fan just strained and strained until the battery was finally dead.
I still have the 10 mA thing going on, and all 5 wiring circuits tested negative for that. But maybe that's just normal, like for powering the Charge Wizard blinking light as 62Overlander pointed out, or some other miniscule thing that I'm not remembering.
Anyhoo- if this turns out to have solved my problem (and I'll be darn surprised if it does not!) I may post the cause of it all in a new thread with a more cause-specific title so others can find it more easily with a search.
Thanks for all your suggestions so far!

idroba posted while I was writing my last post, but I wanted to respond: Your info on the mA draw as regards the converter/capacitor was exactly the kind of info I was looking for- Thanks!
The 10mA reading was just a guess, as the only setting I have on my cheap meter that would allow for the initial 70mA spike is 250mA, so it is hard to distinguish 10 from zero..
And- when I was doing all the mA testing, the skylight was closed, hence no juice to the fan.
You are prescient, my friend, and very helpful- Thankyou for the post!

Is it possible that the draw is on the positive side of the circuit and due to a poor ground some where, not registering on the negative side where the measurements are being taken? I'm thinking of a malfunctioning exterior marker light with either a messed up bulb or messed up ground or just a rusty positive connection. Jim

I suppose that is possible, if it's not the converter/charge wizard, though I think all my exterior lights are functioning perfectly. Thanks for the idea!
I'm just relieved to have figured out the BIG problem, and I hope I didn't weaken or ruin my brand new deep-cycle battery. Any thoughts on this? Walmart said that it diagnosed out fine when I took it in dead, and they charged it. Does a total discharge typically NOT ruin a battery? I don't have a lot of experience with this stuff..

I am so glad you found the problem and figured out when/why it happened (lid open only).

A total discharge does not do a battery any good, even once, but if it did not sit long totally discharged, you probably did not hurt it much. It is sitting discharged for any length of time which will kill a battery capacity, even one time. By length of time, a week or more I would judge.

Keep it in mind when you come close to the free replacement warrantee time, and check it for capacity then. Wal mart is pretty good about exchange at your say so, at least in my limited experience.

I think it sat dead only for one night. I was checking it often (by turning on the "porch" light) since I knew something was iffy...I feel bad about it, and can only hope I didn't shorten it's life too much. My last Walmart deep-cycle battery came with a pop-up I bought in about 2000, and I put it in the AS when I sold the pop-up. It lasted until a month ago!
I agree - Walmart has been very decent with me as well, regarding warranties on their batteries, free testing and charging, etc. And they're less than a mile away. I don't buy much else there, but they are where I go for an automotive battery.

The up-date on this is that since having removed the ailing sky-light fan that was not working but still drawing current, and having fully re-charged the battery the same day, I still show (5 days later) 13 volts with the trailer not plugged in to shore power. For this '70's model with nothing to normally draw any current (besides the tiny led light of the Charge Wizard), this is the normal state of things that I was used to for the last 9 years. So- problem solved, with no readily apparent damage to the battery from the 1 short-lived discharge.
But the lesson here is to more closely monitor and control any possible electrical draws than I did this Spring, when I cranked open the front skylight and completely forgot that a fan was supposed to start whirring rather loudly. I think that all you '70's owners with that type of fan up in there might want to consider getting rid of the automatic pressure switch and replacing it with a toggle switch, or a rocker switch that lights up, maybe in the ceiling right next to the light shroud. If I ever fix the fan motor and put it back in, I will definitely re-do the switch like this.
Happy Camping! We'll be in Moraine Park campground, Rocky Mt. Park, this coming Sunday and Monday nights. Anyone else going to be up there?
