Unless you can find 20 to 40 watt resistors somewhere (?) that will dissipate a
lot of HEAT, no....
The Heater Fuse is 20 amps. Assuming they doubled what amps the heater will
pull, that is around 10 amps load. 12 volts x 10 amps = 120 watts.
The resistors act as current limiters and as such get hot themselves.
At low speed, the motor may pull even more amps....(?)
Those coils get quite hot (Red Hot?)...as can be seen by the fact that they look burned.
The heater box is designed to blow air over those coils to take the heat away.
If you could find some "Nichrome" wire of varying thicknesses, you could use a
Ohm meter (VOM) to cut the wire to the appropriate resistance (
Length) in OHMs ,
wind a coil into the shape as you find them on the Heater Resistor Block,
and then
high temp solder them into place on the Block.
My Heater Resistor Block looks like this (still functional).
Something that might work is the wire out of old
toasters and
hair dryers, etc.
Thin stuff. Each coil in the Heater Block looked to have somewhat different gauge Nichrome wire.
Maybe double it up if need be.
Buying Nichrome wire anymore would be difficult (to find) and you only need a
couple inches - not a roll !
Old Toasters and Hair Dryers at Goodwill, Volunteers of America, Salvation Army,
Value Village or maybe Garage and Yard sales....
