EER Cruise Commander connecting to 2 motors

They are connected in Parallel and as you have noted they may need to be reversed.  I use a 9V battery to verify motor direction and ensure the wires are correct.  For instance try the blue on positive and the brown on negative.  If the motor runs forward hook the blue wires to brush one, if not reverse the connection.  Good luck!

Thanks. The response from EER was "you do not attach four motor wires to the board.  You attach two wires from one motor to the board. Then with two more wires you jumper from the first motor to the second" which sounds like a series connection.  The instructions are not clear on how to wire dual motors. But if I understand you correctly, all four wire (two from each motor) are wired to the Cruise Commander board.

Thanks,

Dennis

Parallel is the way to go, a series connection would greatly limit the top speed and pulling power at any speed.  It may also affect the back-EMF sensing, don't know what effect that might have.

 I will attach all four wires (two from each motor) to the Cruise Commander board, and not " jumper from the first motor to the second"  That's one wire from each motor to Brush-1 and Brush-2, respectively .   Thanks for your help; this site is a great resource.

For MTH engine both blue would be together and both brown.  As stated if the engine starts in reverse just switch there position on the board. G

Thanks, GGG.  I will do exactly that next week when I install this.
