Don't you connect the field to power not ground? I mean, to test if the generator is charging?

If you give it full voltage and rev the engine a bit it should charge like crazy.

Check your wiring for frayed wires, loose connections and corrosion.

It also helps to check out the brushes and be sure they are free to move, and not worn down. If the end of the brush is below the top of the brush holder it's time for new ones (about $10 bucks a set). You can do this without taking the generator off in most cases. I look at them, using a mirror if necessary. And pull on the wire with needle nose pliers after giving them a shot of electronic cleaner or WD40. This usually does the trick.

Tap the voltage reg with a screwdriver handle. Sometimes it works. If necessary you can take the top off the reg and make sure the points aren't stuck, give them a shot of electronic cleaner and drag a piece of white paper between the points.
