I assume using my cheap multimeter I could do the same and check for
voltage?
Yes. Look for changes when you 'modulate' the light switch.
Yes, but not with a "cheap multimeter" - those ones typically pay zero
attention to proper mains isolation despite their self-declared CAT
ratings and have no MOVs etc.
You don't touch any metal parts of a "cheap multimeter" as they are all
plastic apart from the metal parts of the probes.
Leads are a suspect as well.
I was wondering what was constantly draining our car battery, and what
current it was - expecting a few 10's of milliamps drawn.
Erm no.
With a series connection I found I had rather more. Amazon's finest 99p
test leads have a nifty built in detection feature.
Smoke....
(I now have a decent clamp meter that does DC)
