Need Help with a New Holland LS55 with Kohler CV20S engine. No start

[champsin97]

I've owned this machine for 3 years and never had a problem until the other day. Went to start it, turned the key and nothing. I had just cut my grass 5 days earlier and had no problem. I turn the key and nothing happens except for that I hear a "click" up in the carb area. Here is what I have learned so far in my troubleshooting efforts: Battery....measures 12.4 volts across it. Ignition....I am getting 12 volts to the ignition switch and I am getting 12 volts out of 2 of the wires when I turn the key all the way over ( I am assuming that is good). I am getting 12 volts to the solenoid from the big red cable coming from the battery. There is also a small red wire connected with the big cable. There is another smaller wire connected to the solenoid but I am not sure what that is for. QUESTION 1: Should there be a DC voltage there when I turn the key over? QUESTION 2: Would the oil sentry/ sensor switch, if bad, keep it from starting? ( oil is full )

I checked all the fuses I could see and all were good. The PTO knob is in the right position to start. Not sure where to go from here. My grass is like a jungle. Any help would be greatly appreciated.

Brake\clutch pedal switch.

Brake / clutch pedal switch. I was told that was only for the blades coming on. Will it keep it from starting? Where is it located and can I by-pass it? How? Thanks in advance.

Try this: using a test light or volt meter, connect from the small wire on the solenoid to ground. Check for power while holding the key in the start position. You may need to have a helper sit in the seat to override a safety switch. The ignition switch sends 12 volts from the "S" terminal to the small terminal on the solenoid if everything is working properly. Next test: if you have 12 volts on the small terminal of the solenoid with key in start position then check the other large terminal going to the starter while the key is in the start position. Do these two simple tests and report back with what you find.
