If your battery was charged up full when you started you should of been able to run tractor all day and start it several times before noticing your battery was getting to weak to start tractor even if your generator wasn't working at all. I just gave my H a working over in that regard. First thing is first. An H is suppose to have a positive ground. If you put your battery in with a negative ground your amp meter will show a positive charge but actually it is running your battery down rather than charging it up. You can rig it up how ever you want as far as negative or positive ground but you must polarize your generator so it will charge the right way and if you rig it up negative ground your amp meter will actually show a negative charge when charging battery. When you polarize it you have to jump across a couple terminals on generator and I can't remember which 2 it is right off the top of my head and you have to do it after you put battery in and I don't remember if tractor has to be running or not but be careful because things can get hot and burn up really fast if you don't do it right and fast. One other thing. You might check and see if you have a voltage regulator or a cut out. I thought mine had a regulator for the longest time but come to find out it was a cut out. If it has a cut out it has to be manually operated and on my 1943 H it is activated with the light swich. My light swich has 4 clicks to it. Off and first click to activate cut out and generator, Second click to turn generator on high I think and to add the lights on low beem and third click adds the high beem selection for lights. One of the bad things about the cut out is you have to have all good connections with ground and everthing in good working order for it to work and then you have to know how long to leave your generator to charge because it won't tell you when to shut it off and you can burn something up by charging when your battery is full. I haven't messed with a regulator much but I know they are easy to burn up if not polarized right and they are expensive. So make sure you have voltage regulator and not cut out. I hope I have been some help. One other thing, if you rig it up with a negative ground like I did you might want to swich your wires on coil the other way. A guy told me you could damage your coil by running electricity through it the wrong way. I did't swich mine but haven't burnt anything up yet so I don't know if there is any logic to that.
