86 Carrera Wiper Relay Test Question
 

I have a 86 Carrera and the windscreen wipers do not work at all. Front or rear.
Fuses are all good, which led me to believe that perhaps the relay in the front compartment has failed.

At this stage, I have removed the relay; but need help to figure out if the relay is in fact, the problem.
Can I jump certain pins in the harness, to see if the wipers work?
