Electric fans, revisited

[69MyWay]

Joe,

I like your idea. My only critisism is you are now going from bare bones simple to one of the more complicated designs possible.

In the same respect, it is a genius idea, and I am very intersted to see how it plays out.

Keep us posted.

It was fairly complicated, when I started. After staring at the diagram for a while, and changing things around a bit, I've gotten in pared down to only the delay module and two small relays, in addition to the two fan relays that would need to be there anyway. Well, and a single additional thermo-switch, if I add that.

I need to check into availability of the delay module. If I can't expect to easily replace it if it ever fails, I'll look for a similar one from a more modern car. I'm going to do the same thing with the relays - I want to stick with standard GM components that any mechanic would be able to get (or even have in stock), as much as I can.

I agree that simplicity is definitely good: when I first drew it up, it had four extra relays and a lot of wiring. I spent quite a while looking it over to eliminate as much of the complexity as I could.
