Welcome to my world. I'm sparkless myself. Buy a Clymer manual, it's the best $20-$25 you can spend. The manual will walk you through step by step. You are going to need an ohm meter, it's a must have. With the manual and the ohm meter you will be able to chk the key switch, kill switch, and statar. Even though the manual states that you can chk the coil with an ohm meter, they would be incorrect because you can't get a correct reading. You need to take it to a steelership, they will chk your coil for free. I chked mine w/a meter and it claimed that the coil was bad. I posted here about all of my meter readings and a couple of members mentioned that I wouldn't be able to chk the coil myself and they were correct. Took it to the dealer, they chked it and shee was fine. There is not a tester to chk the cdi box. The only way is to remove it and install on another shee. According to the manual, my statar was shot I replaced it last wk and I still don't have a spark. So, the next thing I have to replace is the cdi box .
So, good luck and keep us posted.
