[6pack] Electric cooling fan: pusher or puller?

[Foster, Stan (HP IT)]

Hmm. There is probably a theoretical way to detect if the fan is turning and
moving air but I've never seen an implementation of it. I think most of us
assume that if the fan has power it will run and if it fails it will fail
gracefully and let us know. We typically use a lamp to tell us if the fan is
energized and the temp gauge to tell us if we are being adequately cooled.. If
the car is stationary I know when the fan kicks in because I can hear it and
it moves so much air I can feel it in the cockpit.

Is there an easy, reliable way to wire the system to let a person know if the
fan has quit running? Without a mechanical fan, an electric only set-up could
cost a lot of money and cause heartache.> Date: Wed, 7 Jan 2009 08:24:16
