how can i sort my ignition and electric start?

Ive rebuilt a speedfight 2 100cc, fitted a new ignition and my electrics are constantly on. Ive tried putting the key back in and turning it other ways but it just wont turn off. I have to disconnect it from the battery and its clicking when turning. How do I sort this? I have also wired all of my electrics up but the only one i can't connect is the electric start due to having a different wire on my wiring loom and on my electric start cable.
