Question
I started the bike after its been stored for the winter .The battery I installed was fully charged and started after a few tries .I didn't let it idle long enough after starting it, before I gave it throttle, and it shut off ,so after it did  that a few times I noticed the battery needed to be charged again . Well that's when I made the mistake of connecting the battery charger to the battery and instead of waiting for the battery to charge again , I tried to start it while it was plugged in to the battery. I heard a loud clicking and the bike hasn't been able to start every since.The bike doesn't make a sound or light up when I attempt to start it, only when the charger is plugged in do the lights turn on.Could it possible that the cdi is fried or another part? Please help.

Answer
It sounds like you may have blown a fuse or maybe damaged an electrical connector.

I would start by testing every fuse with an ohm meter or a fuse tester. Read through the manual and make sure you know where every fuse on the bike is before you start - many bikes have a fuse panel with several fuses for lighting, horn, accessories &c and a main fuse in a separate location.

To test a fuse you need to remove it from the holder and connect the leads of the ohm meter to it. The meter should read zero (the same reading you get when you connect the meter's leads together. If you get any other reading the fuse is no good.

Damaged connectors should be easy to spot. The insulation on the wires running to them will often be melted and the metal parts inside the connector will look burned. I would think you only need to look at the connectors around the battery and the solenoid.

The lights come on when the charger is connected? That's strange. Where exactly are you connecting the charger? If the leads are clipped directly  to the lead terminals of the battery it could only occur if the battery is completely dead. If the charger is actually connected to the cables that attach to the battery I would check the connections between those cables and the battery - it is possible that the junction between the lug on the cable and the battery terminal is oxidized and not conducting.
Start by disconnecting the negative cable from the battery so that if the wrench or screwdriver you use on the positive terminal touches the frame you won't get a big spark and injure yourself or damage something. Loosen the positive cable's screw and rotate the lug back 7 forth a few times (the object is to break up any oxidization between the lug 7 the terminal and produce a fresh contact between them). Tighten the positive cable and reconnect the negative and then rotate it a few times to break up any oxide there too before tightening it completely.

I recommend joining a good online usergroup (discussion forum) for bikes like yours. http://www.hondashadow.net looks pretty good to me. Most forums are free, but you will be expected to share what you learn with others in return for learning what they can teach you. You can also form friendships with people all over the world that you have something in common with.
