Beware the Hillman
just some advice
buy a digital non auto sensing meter
its better in the long run and will be handy for other stuff

Beware the Hillman
that's spot on for a beginner

set the meter to AC high voltage (700) I think on that meter
the prod the black on the blue wire and red on brown wire to get 240 or 220 V
then prod the 2 black wires with the probe black probe on outer pin and red on inner pin to give you 110 or 120 volts
if you don't get those results then trannie is now a man and will never cross dress again

Righty, the multimeter has arrived! However 2 things are puzzling me regarding your instructions:
1) I don't see a setting of AC High Voltage 700 - I see 24 different settings split in to 6 segments. Which one should I use?
(assuming the top position is #1, I would've switched it to #20 - it's Red! and says >2k)
2) There are 4 holes at the bottom to plug the prodder things in. Which 2 do I use?
Thankooooo
It's a little blurry, but I think you can make out the markings...

I've added some scribble to show where you need to put the dial to measure Mains level AC, and Where to put your probes. As you are new to this, please proceed with caution and care. Mains AC hurts and can kill you, so make sure you keep your fingers away from the live metal contacts. Good luck
nice one! I'll have a go at this later on this afternoon.
Let's assume the Step Down transformer ISN'T the problem (I know it is the problem, but let's assume it isn't)....
Do I need to change any settings to test other areas in the cab e.g. checking the voltage to the pcb, to the internal power supply, all the output voltages of the power supply etc
I'm guessing all I do is trace where the wires are taking power to, and then prod at various points until eventually I get a 'zero' reading which indicates that power isn't getting any further than that point.
Thanks.

COM stands for common. It's the hole you always use for the black wire.
V/O is the hole you use to measure voltage (what you will do) and ohms.
Never measure ohms on something that is powered on.
mA is the hole you use to measure current. You don't want to do that yet.
10A is the hole you use to measure big currents. Again, wait with that.
At the moment, the right site of your dial is what you need. The upper black part are the DC voltage ranges, and the red ones are the AC voltage ranges.
The number is the maximum voltage you can measure on that range.
Transformers only work on AC The mains power grid is also AC.
Game boards work on DC Usually, they need 5V and 12V. Older pcb's might also need -5V
Connecting the meter to a voltage source while it's set to measure ohms or current will damage it.
The symbols underlined with a solid and intermittend line refer to DC
The symbols underlined by a fallen down S refer to AC
The 3 ranges in black on the right bottom of your scale are for current. You don't want to use those
at the moment.

yep there was. I read it last night, but it flew right over my head. I'd never even heard of a multimeter until yesterday, let alone how to use it. I figured it was best to ask my 'noob' questions here and get some plain english answers which related to my specific issues.
You've all been very helpful so far and I'm very grateful. I won't actually be doing any testing until this weekend mind you, otherwise I may end up rushing around and getting a few shocking results
I'll keep you posted with how my endeavours go.
Thanks
fixed!!! yay me!!! woooo.
Turns out it was the step down transformer that was knackered. So now I've not only got a new step down transformer, but I also rewired it so that it is properly earthed!
phew!
Thing is, now I'm considering getting this:
