Now, let's see you do the same thing with a wiggy. :wink:

That's exactly why I don't use a DMM for most electrical work. A wiggy style meter will load the circuit down and prevent misleading measurements.

And if you drop it from 30 ft. up you don't feel like falling on your large screwdriver.:wink:

Sometimes lighted switches pass voltage even when they are off.

three way do it to. First time it happened to me it took three hour to figure it out. Then realized if I put the ground to the low voltage leg (40v) it went away, then I was like you bonehead it induced voltage..... so I put it all together and fixed the three way that was improperly wired (original call) and went outside and smashed my voltage stick and digital meter. I have never used a digital meter for trouble shooting again 10yrs.. I do use it for other things but not trouble shooting.
