Help with fridge compressor

[zeff]

I just took apart an old fridge to use the compressor for an air compressor. The fridge does not have a capacitor, so i cannot follow similar threads on wiring. I was able to run the compressor in the fridge however cannot get it to run now its been taken out. I cut the power cord leading from the wiring harness to the thermostat and now have 4 wires however I do not know which ones to connect in order for the fridge compressor to run. I have tried wiring in the old thermostat however it still does not work, I think it may be because the temperature sensor has also been cut. I have attached photos so if anyone could shed some light as to what wires to connect it would be greatly appreciated. Thanks.

Thanks for the link, I have however already read that and unfortunately the symbols are different on my thermister. I have C, S & M listed on the rear of my thermister and S, N, L & T listed on the front. Any ideas?

Have you tried looking up the manufacturer's wiring diagram?

Everything is almost ready. The cable that was connected to the thermostat has 4 wires:
blue - neutral
brown - line (the two are for the light)
orange - this one activates the fridge - when you connect it with line it should start the compressor. You need an ON/OFF switch between orange and brown

green - ground

Thanks! Its working. For some reason attaching those same wires and flicking the power point on tripped the circuit breaker. Wired a switch in and its good to go. 300psi and climbing.

wait what?? it tripped the circuit breaker?? that shouldn't happen

[zeff]

Well it tripped the overload in the powerboard. Tried every combination of bridging wires and some tripped the overload as expected and others did nothing. Strange.

[POLAND_SPUD]

Well it seems that you shorted line with neutral. Does this still happen?? It shouldn't at all.

[zeff]

No, not having issue with it now the switch is in. Strange because its switching the same wires I physically joined.

Sounds like it's one of those magic switches.
