very quick update...
The first battery i have tried with this new motor did not start, and I even let it sit for a bit over 20 minutes. This is the same battery that ran the PC fan that I have been posting about.
I tried one of the two other batteries I have, and it started the motor right away. Now here is the interesting part, this battery is a 12V 33Ah lawn mower battery. It has been sitting at less than 1V for quite a long time. I have tried to charge it on my SSG with cap pulser, and couldn't get it to take a charge what so ever. When I hooked up the motor, it started immediately, so I quickly took the motor back off the battery, and after a few minutes tested the voltage on again. Right now, it is sitting there with 11.5V on it
That would be a near instantanious charging of this battery. I didn't even let the motor run for 5 full seconds before taking it off, and I keep testing it to make sure I am not reading this wrong, but it is still putting out 11.5V on the meter.
out of sheer curiosity, I put the first battery back on, waited about 10 minutes, and was about to take it off. I remembered Turion posting that he once spun the motor by hand and got it to start, and just to see what happens, I did the same, and right now the motor is slowly spinning and very very gradually picking up speed!
I really need to catch a few hours sleep, but it will be very hard to relax knowing what I have sitting on my bench right now
If I can pull myself away from the bench, I am going to try to get some rest (recharge my own batteries) and come back to this ASAP. I will test some different loads on Bat 3 and try to find the balance that has been discussed on here, and will report anything that I find.
this is incredibly interesting, and I can't wait to see what comes out of all this next!

just before I hit the post button, I looked over and the motor had stopped. I went and put the fan on battery 3 only, as an additional load, and both the fan and the little motor came right to life! both are fluctuating speed right now. also, I put the fan on the 12V 33Ah battery, and it ran just fine, so that battery did indeed accept a charge nearly instantly...
crazy stuff man...
I added a light bulb (not sure what wattage, as it came out of a drill press that the motor siezed up in) and while it is very faintly glowing, when I applied that additional load, I heard the motor speed up just a tiny bit. Now it is back to fluctuating speed again... Just don't know what to think, this is pretty incredible!
also, when I load down the motor shaft to nearly stopping it, the fan motor picks up speed dramatically. I am still checking the voltage on the 33Ah battery in absolute disbelief, but it is still at 11.5V and does run a 12V load very well. This battery has been completely dead for years!
I took a quick video of what I have going on here, so I could show a scope shot of it running all of this. I am going to wait to post it until later, as I want to run some more tests, and will likely have more to add to it before posting to youtube. I will make sure to get shots in the video of the scope across bats 1 and 2, one on bat3 only and one on the motor by itself also, just so we have a frame of reference to work from. My shot of bat 3 was similar to the photo posted by Citfta, though it is a bit more chaotic since I still had both loads (fan and light bulb) on bat 3.
