[V6-12v] Radiator Fans not switching in correctly...

[Tom Christiansen]

James,

Yeah... That rad fan resistor pack is bloody expensive. I recall
paying $40 at a junkyard for the one I needed for my 1985 5000CS in
1999.

The resistance of a healthy pack is on the order of a few ohms. Maybe
slightly less than an ohm. Thereabouts... A broken pack is pretty
obvious to spot. The resistance will likely be in kohm or Mohm...
