was mowing with simplicity 16gth with biggs and stratton and turned key off and mower would not shut down, I choked it out and now now dash lights, no nothing when i turn the key. the 5 pronged plug that plugs into the ignition has 1 plug that lights up my test light but when i turn the key nothing!! Is the ignition bad or is there something else it could be. Just a novice, need help. can start by jumping across solenoid. could it be a safety switch somewhere, how do i check???
