Followup Powertech 15kw cooling fan

[Pete Masterson]

The genset on the '93 on eBay has the motor capacitor clamped to the
edge of the fan housing. The capacitor on my unit (which looks just
like the one in the photo) is inside a weather-sealed junction box
that's attached to the front (curved) side of the fan housing located
just to the left of the capacitor in the photo.

My coach has a deflector at the front edge of the radiator beneath
the coach. The dust accumulation was roughly aligned with the street-
side edge of the shroud (as the radiator is wider than the fan) --
this is probably an area where an air current eddy forms -- I suspect
that some air (and dirt) is drawn up from the road through the
radiator in the area at the side that's wider than the fan -- then
it's deposited in the 'dead zone' that occurs. I doubt that the
accumulation would ever be significant enough to seriously reduce the
cooling capacity.
