i need spark

[bonehead]

I have a 1985 ytm 200 with no spark. Where do I start to look ? Power to cdi but no spark, also the lights dont seem to be working with regulator hooked up this is my first time trying to fix atvs.

Check for lose wires, possible bad cdi, or dirty altinator. My yamaha tri-moto 175 just **** the bed to.
