Wiring issue 12v vitrifrigo (1 Viewer)

I think I'd class moving a selector knob to 20vdc pretty easy. And an Autoranging meter even easier. But If you can't do that probably best not attempt any repairs

ive no idea of meter sensitivity is but ive successfully used one for work for 50 years lets not too deep with problem solving

It's too easy to dismiss as unimportant until you have explained, with great difficulty, and for the umpteenth time, that a 12v reading on the end of a wire does not mean that the wire is in good order and will operate whatever you connect to the end of it.

No it isn't unless you fully understand the concept of meter sensitivity.

What I meant was, it's difficult to mess up a voltage reading, compared to a resistance reading (which must be unpowered) or an amps reading (which usually involves disconnecting a wire to loop in the meter)

I agree but very often users try to fault - find using a meter and are unable to understand that on its own a voltage reading is meaningless. A multimeter is very useful for measuring battery voltage but close to useless in inexperienced hands for faulting a failed service or appliance. Now a 21W bulb with a crocodile clip connected to one terminal and a probe to the other is much more useful.

As an update (thanks everyone - it has been really helpful!) the wires going into fridge are no longer live so I obvious did more damage than I thought when moving it out.

Just make sure you tape up any spare wires so they can't touch metal parts or other wires. If the wires are broken inside, they sometimes reconnect due to for example vibration and movement, and become live.
