Two things.

First, it seems that, if you take the bms off (which I have enough room to do without taking off the fan), then, if there is enough fluid in the VFC, it should lock up. Correct?

Second, by "lock up" do we mean that, with the engine off, you can't turn the fan because it is mechanically (not through the viscous coupling) locked to the pulley?

Finally, time was not wasted at all. If the clutch is out of fluid, I'll fill it and I should be back in business.

Thanks for your advice and time. ARW
