Huskee Mower Won't Start With Key Switch?

I have a Huskee mower with 12hp Briggs. It will not start with the key switch, but will across the solenoid. I put a new switch new solenoid on. It still won't start with key or cut off with the key after I get it stated across the solenoid. I bypassed the safety switches and it has good ground. I'm out of ideas.
