my ammeter is registering negative even when negative pole removed. Any idea of problem. Could it be a short in electrical wiring? thanks for any help - Pete
 
If it registers negative with one lead disconnected, no current is flowing and I wonder if the needle is bent.
 
I agree that it sounds like the VERY THIN delicate needle is bent. I use a magnifying glass and toothpicks or tweezers to carefully bend the needle back into shape. Put a drop of heavy oil on each of the 2 pivot points. It'll help keep the needle moving freely and offer a very slight dampening.

Don't run the engine with the post disconnected as you need a complete circuit to keep the generator from overcharging and burning itself up.
