That does sound like it's pulsed. Multimeters can't read non-DC signals, you'll have to use an oscilloscope. (Notable exception: 50Hz AC sine waves with the "AC" setting for your household wiring needs).

Interesting stuff in any case!

Might be an idea to hookup an led to that signal.. if the pulse length is long enough you would notice it.

That's actually a very good idea indeed! I'll do that on Thursday of Friday when I have time. Thumbs up!
