Sounds like a good reason to install a properly sized fuse inline with a wire gauge upgrade. Perhaps an alternator upgrade would also be in order? Any voltage drop across your headlight/radiator fan/blower motor supply wire implies waste heat being dumped from the wire. Power = current x voltage. A 2 volt drop in a supply wire with a 20 amp load is 40 Watts wasted.
