F90TLR Trim down problem

I Installed a new trim motor, relay and replaced the ground wire on the bottom of the PTT. Previous motor would only work if I hit it with a mallet.
Now the motor will trim up just fine but will not trim down at all. It makes no noise at all when I press the switch down. I have searched google for hours and still can not find a solution. Does anyone have an idea of what I should look at next?
 
Since you hear no sound, check the voltage between each terminal of the PTT relay coupler when pushing the power trim and tilt switch between the light green (Lg) lead and black (B) lead. If you get 12V, then replace the PTT relay again.

If you don't get 12V, check the fuses for continuity. Replace any that don't show continuity. If the fuses are ok, check for continuity between the battery, relays, and power trim and tilt switch.
