Hello,
My CK2510 did not start today after being parked for several days. Let me provide some background. Tractor has 107 hrs on it.

One day the tractor didn't start. I found the battery dead. (I left the key on "ACCY" I removed the battery, charged it and performed a load test. Battery checks good. Reinstalled the battery and the tractor started. Next, I checked the charging system. Alternator not charging. Just showed battery volts. Found fan belt completely worn out and slipping. Replaced fan belt with one from NAPA. Start the tractor and still not charging. Removed alternator (107hrs) and stopped by an electrical shop. They bench tested the alternator and it checked ok. Brushes good. Output 14.0 Volts. Reinstalled alternator and belt. Started tractor. No alt light on. Drove tractor to my shop and parked it.

8/28: Went to start tractor. No start. Tested battery 13.1 volts. There is a click when key is turned to "start". (Relay?) Removed starter and bench tested. Starter ok. reinstalled. Tried to find a wiring diagram online with no luck. I know there are several safety switches that need to be engaged before the engine starts. One is the seat switch and one is the transmission/gear switch. The trans needs to be in Neutral. Maybe a parking break switch too.

Tomorrow, I'll check for power/continuity in the safety switches. Does this tractor have a starter solenoid? Is there something I missed? Anyone else have this or had this no start issue? Any and all advice is gratefully appreciated. I'll post finding when the job is completed.
 
Update: I went back out to troubleshoot. I didn't find any chaffed or broken wires or connectors. I did get the tractor to start by wiggling the H/N/L shifter. I placed the shifter in Neutral and the tractor started. I turned it off. Reinstalled a cover panel. Jumped back on to start and again "No start". I now believe that the problem lies with the shifter lever and it's position. There's a small electrical box next to the shifter, See photos. Would this be a neutral safety switch? The lever to the right side of the box is the range selector. Back to research.

Is there a way to update my messages without completing a reply? Anyway, I have continued to search and the photos I posted is not the neutral safety switch, I have no idea what this box does.
