[TowerTalk] MOVs in Stackmatch

I am repairing a Stackmatch that was damaged by voltage induced on 
the control lines by a nearby lightning hit.  Most of the traces 
going from the terminal strip to the hot side of the MOVs protecting 
the relay coils are gone.  Do MOVs fail open or closed?  Is there any 
way with minimal equipment to see if an MOV is still good? The relay 
coils all appear OK, so I guess they did their job.
