PWM radiator fan controller

[parsonsj]

Thanks Terry. I've got a Fluke 87 multi-meter on the way. It can read pwm signals.



I'm sending my controllers to Andrew Borodin -- he's got a known working setup on his 67 Cougar, so he can test the controllers. In the meantime, I've rewired my setup just a bit so I can swap between discrete (relay) controls and PWM controllers by swapping out the sub-harness. It lets me continue on the rest of the car...
