If you scout around this blog I came up with a better solution that uses the wall wart and little else of the original charger. http://www.desert-home.com/2012/07/battery-charging-part-3-harbor-freight.html is the link, but sometimes they don't work in comments. [links]
I had one of these on my emergency generator. I was a little afraid of it given some of the terrible reviews. But it seemed to work OK for several months. So I bought another with the idea of modifying it to be used on my antique car 6 volt battery. I opened it up and created a schematic yesterday.
I decided to check on the original unit, and found the LED was out.
We had a wicked lightening storm early this morning. Had a strike very near us and I heard a loud snap like a high voltage arc.
I disconnected it from the battery and open circuit the unit now outputs 19 volts! This would surely cook the battery. I am glad I checked on it.
Any thoughts on what/how it failed this way?
I guess I will return it and get another.

I live in the Arizona Desert, Southwestern USA. It gets hot here, and my power bills got out of hand. This is a journal of my various efforts to bring this problem under control using the cheapest technology I could find. Saving money shouldn't cost a fortune.
I've worked out my modifications to the little charger. Here is the schematic I ended up with:
Here is a picture of the way I hooked it up: more
Part 1 of this project is here, and part 2 is here. [links]

Yes, I'm still working on a good float charger for maintaining my batteries. See my other posts on this here and here for a recap of the project. I finally gave up on the LM7805 circuitry that comes with these devices. The Harbor Freight 42292 charger used to be controlled by a LM317 variable voltage regulator a long time ago. They probably changed the regulator at some point to lower cost or overcome a supply problem. However, it originally was a much better device; it even had a variable resistor in it to allow the end user to tweak it a bit to fit his purposes. I got a clue on this during my searches to get ideas on what to do. Here is the link to a schematic of the original device (link). Notice how different it is from the current circuitry? Just so I have a picture to talk about, here is the schematic from that site:
