I have a Dodge 3500 with Cummins diesel. THinking about electric fans.

Reading all the arguments about how much energy the clutch fan uses versus the amp load on the alternaotor versus "I'm old and I know everythign and that will never work becasue it does not work on my truck"

SO i got thinking about a seperate battery to power the fans.

THis is a 7000 lb truck so a couple of golfcart batteries in the bed would not be felt.

So what if the fans could generate a charging voltage when they are not running?

THen add some sort of low voltage switch to get charging power off the alternator.

So the whole fan system works like a hybird and recovers it's energy whenever the engine is below 195 degrees.

I hope this generates soem discussion.
