What I recommend is an electronic voltage reducer. It's a transistor based device that senses and reacts to varying current loads to keep it's output voltage a steady 6 volts.
I have had extremely good luck with the Ron Francis VR-4
electronic voltage reducer. it's rated for up to 15 amps continuous.
I have installed at least ten of these over the years, and only one has failed - and that one only failed because it got overloaded.
Hope this helps....
That may help very much, I believe that the resistor doesn't work because it's a series wound motor, but, a 6V convertor of the type made for radios in 6V cars converted to 12V will work....(it has regulated voltage output)
Is this what might be considered a converter that you show above ? Thanks
