Cub Cadet LT1042 blades won't engage

[cartoonchikn]

Mower cranks/runs fine, but blades won't turn/engage. I here a click when I pull the PTO switch out. I get 12 volts all the way to the PTO clutch. What can it be? I'm a DYI guy. Not a mechanic.

12V plug to frame or across the plug terminals ?
If you are lucky there will be a break in the wire between the plug & clutch solenoid.
If you are unlucky then it is new clutch time.
