The thing that happens in a 6 Volt system, is that 2 times the Amps are needed to do the same "work". So consider the following, 6 Volts and the same motor Resistance. High speed Amps is 1.9. The 6 Volt motor must have a lower Resistance or it would be slow and slower. With the same Amps(3.7) a 6 Volt motor would have to be close to 2 Ohms.
Below are Ohms readings & pictures of a (
ARK LES) 6 volt, 3 speed switch resistor.
Below is a resistance TEST going thru the switch. Switch position OFF open circuit,--------------------
no reading Switch position HIGH closed circuit, no resistance,-
0 ohms Switch position MEDIUM closed circuit,--------------
1.1 ohms Switch position LOW closed circuit,------------------
1.7 ohms Below is a resistance TEST of the resistor. Resistor tap 1 to Fan motor lead ------
0 ohms Resistor tap 2 to Fan motor lead ----
1.1 ohms Resistor tap 3 to Fan motor lead ----
