Electrical Issues

[Phil]

hi guys! I have a 150cc jmstar scooter and its having some electrical issues. Its been starting kinda rough, like there isnt enough cold cranking amps to get it goin. but eventually starts up. I had the battery tested and its testing great. I did buy this scooter about a month ago with only 65 miles on it. The old gentlemen I bought it from rode it for about 2 weeks back in 2008 and it has sat in a storage shed since then. Up until he sold it, I believe he had it on a charger occasionally. Now when I get it started, the head light, tail light, and dash lights are super dim, even with cranking the throttle the dimness doesnt change. But when I put on my brights (passing switch) its bright as day, but when putting on brights to set them on bright, its dim as the other lights. Ive been doing some research and have read to check the cdi and the stator. I havent done either yet, but was wondering if there might be anyone to have any other advice. Thank You guys!
