Thanks, there is no continuity between M- and B-. The motor works when jumped straight to the battery, it draws 0.8A at 12V DC when jumped straight to the battery.

The motor should be connected straight to the battery on the '+' side, and connected to the MOSFET Drains on the other side (M-), correct?

When you tested yours with a light, were you able to use the throttle pot like a dimmer? My understanding of the code that is in mine is the ATMEGA wants to see current develop (a couple hundred amps at least), and if it doesn't it just keeps ramping up the PWM until it does, or it reaches full throttle.

So, if you had a light hooked up, I would think as soon as you started turning the pot, the light would begin burning dimly, then shoot up to full bright pretty quickly. Is that how it would work?
