It depends on how thoroughly you want it tested.
Slap it on a fan and let it run all day or put it in the car and drive a few hundred miles?

Andrewh has a new style fan in his car. It's also a different shroud so the fans we use won't bolt up. We would have to test the controller on his existing fan.
I can change to an old style on the hot rod but it's not running yet. Close, but not there.

My concern is powering the fan for a long time without burning it out. I think that if you can get it to run more than 5 or 6 hours straight then it's done.

If you can't supply that kind of amperage, I guess we can slap it on the hot rod and try to fire it up ASAP. If it'll run all day long we'll be set.

If your temp sensor lead is something common or easy to tap then we can do it now.
