Default Re: Transistorised Radiator Fan
I’m definitely no Jason ACT. :-/

Killed the unit dead trying to remove the coating.

Plan B came into action. Hotwired the fan after fully bypassing the control board. Set it up to run always on at least low speed, via a fan speed resistor (not unlike the BF). Used a Davies-Craig controller to bypass the resistor for high speed operation, set to 91° probe temperature.

One problem remains. Without a return signal from the fan motor, the AC clutch won’t stay pulled in. So I need to work out how it can be spoofed.
