I need a lil help wiring my two engine fans to one double throw switch (hi&low).
I would like for one fan to come on when I place the switch to low, and both fans to can on when I place the switch on high.
I know there's gonna be an connection between the two fans, but I feel that the connection would complete the circuit of the second fan, on low!?!

Thanks
Ken

You need a relay for each fan and then you need to use a diode on the switch just like a headlight switch in a painless panel.

Thanks Nelson,
But I'm still a lil confused, are you saying this?

That'll work. Make sure that the diode stops current from the low side to the high side of the switch. Then when you hit the high side it will energize both relays.

I see where you're going!!!

Thanks Nelson!!!
