Cooling Fan Switch

The bottom switch on my 74 L is a blank "dummy" switch. You could use the position for anything. As far as the cooling fan wires go, I have no idea. My car does not overheat and I have no idea if the fans even work. I am operating on the "if it aint broke , don't fix it" principal when it comes to the cooling system.

Captain,
THIS SWITCH IS USED ALOT TO INSTALL AS A BYPASS TO THE TEMP SWITCH ON THE RADIATOR.
SO IF YOU WANT TO USE IT THIS WAY YOU WILL SPLICE INTO THE HOT SIDE GOING INTO THE TEMP SWITCH AT THE RADIATOR OR AT A HOT POINT ON THE FUSE BLOCK. THEN YOU WANT TO SPLICE INTO THE OPPOSITE SIDE OF THE RADIATOR TEMP SWITCH, WHICH LEADS TO THE 2 RELAYS, TO TURN THESE ON.
NOW YOU HAVE MANUAL OVERRIDE.


MARK

The radiator temp switches actually switch to ground. If you connect a hot lead to them you will have a direct short.

I pulled out the panel and there are no wires going to this switch at all. So I assume it is there for looks?????

My bottom center console switch has the wiring for the manual switch...I'm changing to thermostatically controlled fans....that way if I miss the guage warning, overheating isn't missed, I'm pretty sure that's why manufactures do it that way. Not sure why anyone would want it any other way?
