My Nova 115 cc has never properly charged the battery, as I always had to charge it manually. It is a 2005 machine, 8500 Km's. Finally I decided to inspect why it was not charging. It appear that the alternator (magneto) has 3 windings,
1 for all the running lights, 1 for the CDI ignition , and a winding for the battery charging. The lights and the battery charging is one winding with a centre tap. It seems that my particular bike had
2 opens in the charging leg of the winding, a problem from the factory,
I repaired the opens, and it is now charging according to spec, .1A - .5A. If you are having similar problems, check the outputs of the alternator with an AC voltmeter before spending lots of money. Use the diagrams in the service manual, they are helpfull
.
Good luck.
