2001 Gem Contactor not pulling in

Trying to find some help as to why the contactor no longer is engaging. With the key on there is no longer beeping from the ebrake either. I am guessing that 12vdc is at the micro switch and when the brake is released it sends 12vdc to the contactor. Not sure what voltages should be on the 3 wires to the micro switch. Is there a place on contactor that I can send 12 v to? Should I be looking for a blown fuse?
