    Something is fishy if the thing draws 60 amps and squeals the belt when the fan kicks on......dont have a fiero manual to see what the fan is fused for. You say that it has two speeds and you have high speed wired now.

    What year fiero is it from? the 84 fan motor uses a ceramic resistor and the 85/86 does not.....not sure how the resistor is wired in but that suggests that the 84 fan uses the resistor for the low speed whereas the later motor must have two input wires.

    Suggest that you measure the current draw on low speed. Most electric fans pull 15-22 amps. Could the fiero start the fan on low speed and then, after it is running, change the speed to high using a relay? It doesnt make sense to have a low/high speed without beginning in low speed.
