They haven't worked properly for a very long time.
But i was running them pikey style with the ac switch and bridged pins 1+3
However after about 4 years that has stopped working. I bave re done the cable bridging.
No luck.
I assume there is something more fundemental going on.
Neither fans work when the ac switch is on. And the dont work when i pull the temperature sensors either.
Where should i begin?
