cub cadet ltx 1046 solenoid wiring
 

Starter was only clicking when I turned key. Put on new starter and solenoid and now it does nothing. Have new battery, fuse and switch also. Have a red wire that i don't know where it was connected . Could this be the problem.

See my attached photo, it looks like the red wire could have possibly went where I had it circled:

It would be helpful to check, and follow the wiring diagram.
Usually they are found on the 'net if you haven't already downloaded it.
That will also help when you are systematically checking why you have the original problem.
It is always better to check and test first, before firing the parts cannon at a problem.
Sadly, in todays world of poor quality replacement parts, near 1/2 of parts are either counterfeit, not OEM and/or defective right out of the box.
Luck!

good guess
