I have a 9-N. I put a new battery in, had the generator rebuilt and it seemed to solve my starting problem. Then I left it sit for a couple weeks and now I'm having trouble starting it. I have to jump it to get it started. It seems like the generator is charging, according to the guage, but when I turn it off ,I can't get it started without jumping it again. It's a 6 volt system. Battery and generator seem to be good. Any thoughts? Also when I go to start it all I get is a sound like something is shorting out. (One little snap).
