I don't think that a continuity check will help. If the bulb is blown = no connectivity. If the fixture is corroded/bad connection = no connectivity.
I might be wrong on the blown bulb but that's my take on it. I could check with the multimeter that you are getting 12V at the base of the mast where the lights connect. That way you at least know whether the problem is on top of the mast (blown bulb, bad connection) or somewhere more accessible (between your panel and the mast). Set the multimeter to DC and put the positive and negative leads on the appropriate wire connections wherever your mast wiring goes to .. should read 12.something with the power on. If no reading then your problem is not on the mast.
