Help me.. 91 trx300 4×4

Oky doke,

Have a 91 Trx 300 4×4 not starting with the button.. The start solenoid has 2 posts, one to the battery positive and one to the starter. The solenoid has a two wire pigtail going to the main wiring harness. One yellow with red stripe and one teal with red stripe.
There is 12v at the battery post, and there is 12v at thestart button on the handlebar, when I hit the start button there is 12v at both wires in the pigtail, but nothing at the starter post of the solenoid so no starty for me.. switched solenoids 3 times.. then I thought wheres my ground??

Are both wires in the pigtail supposed to have power or is one a ground? and if so maybe do you know which?

Any help would be awesome…
