After years of avoiding the weight of an electric fan and heavier alternator, I've got a combo I think I can live with. (I prefer a lightweight mechanical fan setup for the simplicity, low weight, reliability, and stock look, but with my front mounted steering rack, the mechanical fan location options have been very limited, and the shroud shape modifications necessary to clear the rack have finally used up all my sense of humor.) The "new" lightweight radiator and (modest current) electric fan seem to do a good job of keeping the engine cool, and now I'm working on the fan control board (just a transistor and a few discrete parts I have laying around). For this first go-around, I'm doing a manual "turn-on" of the fan (I'll go fancy later, if necessary, but I like to keep the visuals clean of excess wires and sensors on my antique engine). I just need a voltage tap-off that I can use as a signal to tell the fan control board to turn on the fan. My first thought (subject to change or improvement) is using the heater fan control (just turn the interior fan to low to enable a voltage to the fan control board), or turn the parking lights on, or whatever. Just looking for ideas of where to get an easily accessible signal, preferably from under the hood.
Thanks!
