OK gang I got the tractor running. I posted earlier about my starting problem. Thanks for the help. I want to share what I learned in hopes that somebody else can have a "take away".
When I turned the key to start nothing happened. I had checked battery and such. I could jump to the armature post on the starter and it worked.
I checked the starter solenoid. First I checked the wire from the key switch. It had 12vlt when I turned the key.
But I never heard the solenoid click.
I pulled solenoid and but 12volts to the input side (from battery) and then 12 volts to the small pole (from the key switch) I heard the click.--ok good
I then checked continuity between the two big posts with the solenoid engaged. I had continuity there. good
I then checked how much voltage was actually running through the solenoid. I was only getting 1 to 2 volts going through it.
I guess what I learned is that even if you have continuity through the energized solenoid, you may not have enough power going through it.
Anyway now the tractor is running. Thanks again gang.
