Matt, I wasn't able to do the test on the isolator as the terminals were so rusty I couldn't budge them and didn't want them to snap, they felt like they might.
..also not EXACTLY sure what you are saying here: "If you don't get a difference one way and not the other, things are good."
Could re-phrase that please? 
thanks
Larry

If you were good to there, pop the wires off the islator and set the meter to resistance. May be marked as Ω.
Check between the center and both others one way and then reverse the test leads and do it again. If you don't get a difference one way and not the other, things are good.
Isolator failures are rare, but do happen.
