Thanks, Dan! My thoughts exactly! I'm going use the 12-volt motor and see if I like it as is for the high speed. I'll then use a 1.5 ohm resistor (bought specifically for reducing 12-v for the original 6-v motor) on a switch to give me a low speed.

I know the resistor can get really hot but the one I bought was advertised for this purpose.

I had one of those variable resistance (fan speed) switches like Bill showed but it developed dead spots and the clamping thing would bend and get loose. 2 speeds are fine with me. That's what I had for my 6-v motor.

The resistor will be in a metal electrical conduit box inline with the driver side tubing so heat from the resistor is used on the driver side windshield.

Thanks, guys!
