Drive motor on Mastercraft MIG welder stopped working.

Scott, how can I tell which contacts are normally open? There are 2 wires, 1 white and 1 black that connect to relay. The connectors on top of the relay arent marked +ve or -ve. Also you can see the connections/solder on bottom side of circuit board where I'm pointing(see pic).
I'm assuming these are for the connectors on top of relay?
4 points of contact, trying to figure which ones to test?
Thanks!
Steve

that clicking noise is probably a relay controlled by the trigger. if you can bypass the common/normally open contacts on the relay without pulling the trigger and the motor turns you have a bad relay, if it does not you have a bad connection to the motor or a bad motor
