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?

Thanks!

Too technical, forget the meter. First, if you have a Leviton dimmer, it's
a pos, so just get a Lutron of your choice and replace it. When you have
the existing dimmer out of the wall for "testing", remove it from the
three wires, noting the common wire. Touch the common wire to each of the
travelers. One of the two connections should turn on the light. Flip the
other switch in the circuit, then touch the common to the travelers again,
and this time the other connection should make the lights come on. If
things don't happen as I describe, you have a wiring problem


*I agree with RBM. Throw away the dimmer and stop using a VOM for any house
wiring. Change the dimmer to a three-way switch to see if your problem (You
didn't specifically state what your problem is) is corrected. You must
identify the common wire in the switch box. Don't go by color code.
