A picture would sure help here, all the analog meters I've ever used are single swing to the right.
*SLAPS HEAD* oh wait, you're talking about the ammeter on the tractor! STOP EVERYTHING, hold the presses. Step 1. Acquire a multimeter, one that reads VOLTAGE. The ammeter on the tractor reads amperage. If the tractor isn't running and the lights are on it should swing to the left, thats normal. If the engine is running you should see it at 0 or to the right, if its swinging left you're in discharge. Being in discharge just tells you that the battery isn't charging, it doesn't tell you why.
Get a multimeter, put it on the battery, red wire on the multimeter to the + terminal on the battery, black wire on the multimeter to the - terminal on the battery. Should show you 6+ volts. If it tries to swing the other way (or if its a digital multimeter and wants to read -v) then try the connections the other way round.
I think its HIGHLY unlikely you've completely reversed the polarity of the battery, sometimes a cell will reverse, if that'd happened your multimeter would read ~4v. If thats true try charging the battery overnight but it probably won't help and you'll probably need a new battery.
So lets assume things are good and you've got 6+v when looking at a multimeter hooked up correctly. If you've got the tractor running and the ammeter still says you're in discharge it'll probably be doing it all the time, when you put the lights on the motion just gets bigger... If thats true you've probably (but not definitely) got a bad regulator, they're sort of spendy but not too bad and a relatively easy thing to check.

Today's Featured Article - Product Review: Electronic Ignition - by Staff. Oil, for example has come a long way in the last 50 years and I don't use anything but the latest API grade available. I've heard the arguments for non-detergent oils but would never trade it for today's formulations. Paint is another, the modern acrylic enamels are great for resistance to grease and fuel stains, retaining their shine and they last forever; unlike enamels and lacquers . Still another is the alternator. No doubt using the original generator keeps the tractor pure, but for thos
