Hi Guys:

I have a set of twin pusher fans that came with ERA #375. These are the type that mount in front of the radiator. At present, my ERA has the splitter wing in the nose and a single large puller fan behind the radiator.

I am aware that the wiring harness accomodates both the puller and pusher fans.

However, I would like to set up the new pusher fans on their own independent circuit with their own flip switch. I really do not want 3 fans running for about 6 minutes when I pull into the garage after a run. Am I being too cautious about having 3 fans running?

Bob, what is the best way to wire these fans independent of the puller fan?
I just want to turn the pushers on or off with a switch, with no thermal switching activation (via the water temp switch on the puller fan circuit).

What is the best way to protect the proposed new circuit with a fuse? Can I use an existing fuse?

Should I use a fan relay? What are the pros and cons of not using a relay?

Sorry for all the quesitons, thanks so much.

Cheers,
