No Power to Smoke Extractor

When you open the doors you can check the clear relay that does NOT have a red wire. 

You should have 120v across the coil A & B, and when this happens you should then have 120v on the black wire at the S/E to ground.  

If you have 120v on the coil, but no power on the black to ground you're relay is faulty.
