I have a digital multi meter from TLC
http://www.tlc-direct.co.uk/Products/TMM3800.html

I had to change some 12v 35w halogen lamps today & one wouldn't
work. I set the meter to 20v DC & tried to measure the voltage at
the porcelain cable connector. Nothing.

Tried to measure the voltage on the one next to it, which was on at
the time & still got nothing.

Is my multi meter broken or is a digital meter no good for this sort
of thing? If the latter, what do I need to buy?
Try switching it to AC... :-)

Doh!

What a pillock I am. Automatically assumed 12v would be DC.

Not entirely... worth noting that many lighting "transformers" these
days are in fact switched mode power supplies. Some of these will
shutdown in the absence of a load, so measuring the voltage without a
bulb present may also get you nothing even if using the correct range.
