Still need some help, buggy won't go

Hello again all,
Here's what I have. I have a 2010 EZ GO with a TXT 48 speed controller.

It will not move. The solenoid has power on the positive side from the key switch but going from the positive side of the battery to the negative side of the solenoid there is nothing. The solenoid does not click when the pedal is pushed.

The FNR switch is wired and working correctly. There is 51 and 49v on the solenoid on the larger poles.

I recently replaced the speed controller with a used one from a reliable source who claims it is good, and I'm still experiencing the same issue so I'm assuming it's not the controller.

Anybody have any suggestions?
Thanks!
