Bob,

To proof out the fan motor itself, pull the red conductor from the radiator
fan resistor and feed 12 V. into it.  To single out the thermoswitch and to
check the fan motor along with the other cooling fan circuit components, pull the
connector from the radiator thermoswitch and jumper from the black to the
red/white conductors and then from the black to the red/blue.  If it is the
thermoswitch that's hinky, you'll get both fan speeds with the jumpers.
