Be aware that the wiring to the fan resistor is not rated to carry the full amperage of the cooling fan. If you bypass the resistor, the wiring will overheat and can melt the insulation off or cause a fire.

The torpedo fuses are known to have connection issues. If you have the original aluminum fuses (silver or grey colored metal strips), hit the trash with them ASAP and replace with brass or copper ones with ceramic bodies. Clean the contact points in the fuse box with a wire brush or something before installing the new fuses. The majority of electrical "gremlins" originate in the fuse box solely from crappy fuse connections.
