So Folks I finally got a video posted that shows Mercedes Benz fan in
action on my test stand. The input RPM is a constant at 2600 throughout
the whole session.

FOUR SEGMENTS OF THE VIDEO SHOW:

1) SPOOLING AT 2600 RPM, NOT ENGAGED (10/15 SECONDS)

2) SPOOLING AT 2600 RPM, ENGAGEMENT (10/15 SECONDS)

3) SPOOLING AT 2600 RPM DURING DURING DIS-ENGAGEMENT (60 SECONDS)

4) SPOOLING AT 2600 RPM AFTER COMPLETE DISENGAGEMENT (10/15 SECONDS)

REMEMBER YOU CAN HAVE A SENSOR TURN ON THE CLUTCH OR A DASH SWITCH.

site,...........please

I have a minor addition to Tom's post.
"REMEMBER YOU CAN HAVE A(NY) SENSOR TURN ON THE CLUTCH OR A DASH SWITCH.)

In the near term future, I plan to use the temperature into the water pump and the outlet of the A/C condenser both as control signals. Someone with a 7747 processor you enable one of the included analog switches for this function.

I strongly suggest that you include a visual indicator as the fan noise is very different and you will not be certain of what that new and non-impressive noise relates to.

Matt - near 3k on the new fan and still impressed.
