Hi,

We are suspecting that our 3-way dimmer by Leviton is defective. We
are trying to run connectivity tests with a digital voltmeter, and
very high resistance (1.6MOhms). Perhaps the mechanism in these
devices is such that it cannot be measured with a cheapo digital
voltmeter?

I think it likely is solid-state switch/dimmer, not mechanical.
