Customer: replied 10 months ago.
Thanks!
To be clear, thats looking the back of the receptacle for the seat switch plug?
Any other ideas about the tractor being dead?It was running fine.
Expert:  Curtis B. replied 10 months ago.

Do you have battery voltage to the key switch? DO you ear the fuel solenoid click hen you flip key on and off? No click from fule solenoid, no voltage at key. Check the ignition fuse behind the engine, mear the starter solenoid.

Customer: replied 10 months ago.
I don't know if I have battery voltage to the key switch.
No sounds at all. Battery is good.
I did check the 20 amp fuse- its good.
Expert:  Curtis B. replied 10 months ago.

Power for the keyswitch has to come through the fuse and fuse holder, check for voltage past the fuse with voltmeter or test light. You say battery is good.?? If you jump the two cable terminals on the starter with old screwdriver will starter turn engine? This is quick test of battery, cables and starter.

Customer: replied 10 months ago.
Ill check the voltage past the fuse.
I did try to jump it with a screw driver and got no spark. Battery is good, checked it with charger and a voltmeter. Thats why I took the switch. I was sure it was a bad...
Expert:  Curtis B. replied 10 months ago.

If it will not jump at solenoid, you either have no voltage at the solenoid, or your starter is bad!

Customer: replied 10 months ago.
If the starter is bad wouldn't the solenoid make a sound?
Expert:  Curtis B. replied 10 months ago.

No, you are not using the solenoid to make the connection. To check solenoid you would jump the cable connection, to the small switch wire on the same solenoid.

Customer: replied 10 months ago.
Thanks Curtis.
Ill give it a try Saturday morning!
