Reply to "electric fans (generator?)"

Dave asked me to comment on the RFC.

The diodes that used with the relay's have a voltage drop of 0.7 Volts to 1.0 Volt this lowers the speed of the fans due to the lower voltage.
The RFC also utilizes diodes but used in a different way not to lower the voltage but to return the unused power back to the battery.

In the condition when the A/C condenser is in front of the radiator the air flow should be as high as possible since A/C is a differential heat mover, the evaporator is proportional to temperature of the condenser.

The A/C terminal on the RFC is to force the RFC to drive the radiator fans at maximum speed to cool the front condenser. Since the fans are some distance away from the condenser and the engine radiator acts as a restrictor, the fans are not as efficient as the factory arrangement in addition the heated air from the engine radiator is less dense and does not move as well. (fans are constant volume movers not constant mass flow movers)

The A/C terminal on the RFC should not be used when the condenser is in the factory configuration.

I hope that helps.
I hope to see everybody at POCA this year, the event sounds like a lot of fun.
