OOps, Sorry, Dave, the pic finally painted and your last comment posted while I was still writing.
Definitely do the ground leakage current test that I just described. It is always possible for something to ohm open at a low voltage but to have leakage at power line voltage, causing sparks. You have to have the scope probe grounded to the generator in order for any reading to make sense. Sparks, especially big sparks are bad. Best way to protect the scope and gen is for both to be grounded to the same outlet.
The other thing that worries me is the 8Ohm resistance between the probe output and ground. Ohm that again while changing the "output multiplier". If the resistance does not increase with the multiplier value then something is wrong with that end of the circuit.
