I bought a Takeuchi TL150 (2002) not long ago. The previous owner had replaced the key switch with a universal and it went bad not long after I got it. I replaced the switch with an identical unit and wired exactly as it was done before. Now when I turn the key to "ON", I hear a buzzing sound, coming from what sounds like under the left control tower. If I try to crank it, I'm getting a clicking coming from the left side of the engine and nothing turns over. I thought it would be the starter solenoid, but I believe that's on the right side of the engine. I have a good battery with 12.5V. Can anyone offer any help as to what over there is doing the clicking and the buzzing?
