Does this PWM the negative or positive motor lead?

There are two motor terminals and two power supply terminals. Your motor should have two wires; connect them to the motor terminals. Reversing the motor wires reverses the rotation direction. Do not connect the motor's ground to the power supply ground.I used this PWM on a parade float, where I controlled the speed of an automotive window motor as it spun styofoam "gears" for visual effect. Since the gears were large, I had to run the motor near the minimum PWM setting. There were six window motors total, each with its own PWM. I ran 12vdc plus and minus in a parallel loop around the float, with a master switch to turn on the entire circuit. The float won the parade's award for best animation.

It does have the leads labeled you will have to check rotation once you start. To change direction all you do is switch the leads

the positive. makes a square wave that goes from 0 volts to your input voltage.

Yes. If anything physically causes the motor to stop turning, it will automatically reverse direction.

Chris, Most of these DC power supplies are center positive. The connector configuration (polarity) is always displayed on the front or the back label on the PS.

No. But the leads go from the bar to a switch of 5 or 7 patterns can't remember. Then for the switch it is a lead of positive and negative.

The way I got this to work was to plug everything first including the receiver link, the power red wire is positive and black wire negative (I use 19.2V Craftsman battery), the motor (the two reds are positive for the two motors and two blacks are negatives) and then turn on the switch on the ESC. After that the ESC responds to remote commands via the receiver.

The load goes whatever it is you wish to control, power on. The + is the positive and the - is the negative which will also connects to the device negative.

Thanks, i'll check for the switch on the back tonight. i'm sure the polarity is correct, red to lead (+) and black to ground (-) right?

It's the polarity which is reversed and don't ask me to explain that. I finally gave up and started using batteries. It works fine and the batteries last a pretty long time. Good luck.

I am guessing "NO" since I originally had the wiring polarity hooked up backwards and didn't have a reading.
1550034
Yes, for a parallel connection it's positive to positive and negative to negative and then on to the charge controller.
1510637
No it does not. Go back and check your wiring you might have reversed the polarity.

If this is a new install, then I'd check that the input voltage setting matches the power being supplied to the motor.

It all depends on the type of DC motor you use.If the motor will run directly from DC power source, such as a small battery, in both directions (by reversing + and -) then it will also work in both directions with controller. I am using this controller with dad switch. HOWEVER THE SWITCH TO CHANG POLARITY NEEDS TO BE PLACED BETWEEN CONTROLLER OUTPUT AND MOTOR. IT WILL MOST LIKELY NOT WORK IF DPDT SWITCH IS PLACED BETWEEN POWER SOURCE AND CONTROLLER. I MYSELF DID FIND A DC MOTOR THAT THANKS WORKS VERY WELL.I CAN CHANGE THE DIRECTION OF SHAFT WITH DPDT SWITCH AND VERY THE SPEED IN EITHER DIRECTION WITH THE CONTROLER. I HOPE THIS HELPS.

Mine was clearly marked. From left to right (looking at terminal end of board:Gnd ( battery negative)motor (load) negative -motor (load) posative +Battery posativeHope this helps

Only thought I have is that you have the polarity reversed on the battery leads. If the leads are correct, the controller is faulty.

Simply connect the positive and negative tabs of the motor to a DC power source (5V-12V). Changing the polarity will change the direction of rotation.

2 posts in middle are for positive/negative DC Input. The two outside posts are for positive/negative DC output to motor. Switch just reverses polarity on those 2 posts.
