If you will look closely at the wiring diagram in the manual I linked to, you will see wire color identification chart (B=black, R-red, Y=yellow, etc.) in the lower left corner. The wire connections to the thermostat and to battery power are shown just above the color chart. The yellow is -12vdc (ground) and the red is +12vdc (power). The red goes to the control board (module board) where the fan relay is located. The relay connects the red input power wire to the motor's red or 'hot' lead when the thermostat is activated. The black lead of the motor is connected direct to the yellow negative wire at a terminal block (ground terminal).tregrad said:
If you connect a wire (use 14 ga. or larger) from the yellow wire to the negative side of the battery and a wire (also 14 ga.) from the red lead on the motor to the positive side of the battery, the fan should run.
To test to see if the furnace is getting 12 vdc power in the first place, measure the voltage at the red lead where it comes into the furnace with the negative lead of the meter to the yellow wire. You should get about +12 vdc (or battery voltage). If you do not, the problem is in the wiring between the furnace and the battery. It could be a blown fuse, a broken wire or just a corroded or loose connection in EITHER the hot lead or the ground.
