On that seat switch one set of contacts is normally closed the other is normally open. I solved my main concern. The PTO does not cut off when I dismount. Putting the parking brake on when I do is a minor inconvenience.
Is it a repeated clicking? If so, it is a power issue.i have an sc2400 it started this morning but now it does not start, i ture the key and all it does is make a quicking sound & its not the battery
