Right, Tim, I'm not totally sure about ripping out the original resistor and switch just yet... I reckon Andy wants to keep it all proper and original, and he's still working out how the bloody thing is wired lol. Might be worth him finishing the continuity checks first, then swapping in your 3-speed setup if the blower turns out to be dodgy

Almost done with the continuity tracing. I’ve also compiled a series of if/then combinations to see what functions when power is applied, it’s about 3 written pages long. I’ll test it out tomorrow, the challenge is to decide whether power is first supplied to the thermostat (2 terminals) or to the blower speed switch with 3 terminals on it.
The unit has 3 leads, I assume one for power to the control panel (it’s fused), the two others would connect to the fan and one which would trigger the compressor clutch
I need an electrical engineer, so many combinations!!
