Thanks. I'll screw a batten fitting to a piece of wood, been meaning to do that for a while. I knew there was a reason to keep a few old incandescant bulbs...
I've got quite a few saved transformers and have been connecting up the ones that I know the primaries are 240v but am having trouble working out what's going on with secondaries where there are multiples. I'm getting AC volts readings between secondary wires that, when tested for resistance (not powered up) don't appear to be connected. I'm guessing capacitive coupling maybe? Was thinking putting a light bulb for a load might give me a better idea of what's going on.
I have a nice little (~50VA) toroidial that is obviously 'double 120v' as two primary wires are soldered together and have heatshrink over them. (I removed it and tested resistance and it reads like a centre-tapped winding.) However it's got four secondary wires and I'm damned if I can make sense of whats's going on just with the meter. (Tested for resistance unpowered then AC volts when powered up.) I'm hoping loading them will help.
Cheers,
