Review: FWD- Reverse switch failed - FWD REV switch failed second use . i can still get motor to go FWD but not reverse . Not sure if it's a controller problem or the switch that went bad . for now i'll live with the FWD only but will end up replacing this with a better motor controller .don't want to buy just a switch if the problem is the controller. Edited to note that seller is stepping up and sending a new controller . I't good to know they will reach out after the return date and give a solution
Review: Smooth Speed Control for a Power Wheels Upgrade - Smooth Speed Control for a Power Wheels Upgrade Used this PWM DC motor speed controller along with the DeWALT battery adapter to upgrade my grandson’s Power Wheels, and it works exactly as I hoped. It lets me dial in the speed so the extra power from the 20V battery doesn’t turn the car into a rocket, giving a nice smooth takeoff instead of a hard jerk. The knob makes it easy to fine‑tune top speed for different ages or surfaces, and once set it holds that setting reliably. Wiring was straightforward for a basic 12V system, and everything has been running cool and consistent. For projects where you’re adding more power and want control and safety, this is a solid 5‑star add‑on.

## Features

- ♕【Technical Parameters】 Input supply voltage: DC 10V-55V; Rated current: 40A; Max current: 60A; Speed range: 0%-100% ; Apply to: DC Brush Motor
- ♕【CW/CCW Function】The switch can provide clockwise and counter clockwise rotation choice. With this latching switch, you can control the rotation direction easily.
- ♕【Excellent Heat Dissipation Performance】 The enclosure of the speed controller for motor is an aluminum enclosure. Aluminum shell is very strong to prevent damage, holes on its side and top which are helpful for heat dissipation.
- ♕【Easy to Operate】The stepless motor controller has a simple potentiometer knob adjusts the motor speed from 0% ~ 100% smoothly. LED display screen shows the motor speed from 0% to 100% of the rated speed.
- ♕【Application】 The DC motor driver can be used on brush motor speed regulation, light dimming regulation in the DC circuit. Note: The motor can not be used in electric vehicles.

## Questions & Answers

**Q: can this pulse 12v , would it be ble to pulse 12v injector for cleaning
?**
A: The voltage of your injector is between our controller voltage range (10~55V). If your injector is with a DC brush motor and the rated current is below the 60A, HARMNEE pwm motor speed controller will fit for your injector.  The rated current is equal to the rate of power divided by voltage 12V.

**Q: Why is there a 3 way switch for this?**
A: one is for turning off the motor and the other two are for forward and reverse.

**Q: Can it be used with arduino to control motor speed and direction?**
A: I can't imagine why not as long as the Arduino project meets the volt and amp capacities of the Controller.

**Q: Lemon? Two right most terminals wired to 20V battery but the voltage across the two left most terminals always 20V no matter the % of pot adjustment.**
A: unplug the pot and connect a meter to center leg and either side legs and check ohms clime as you turn the knob. Make sure all connections are correct. If pot works then controller is bad.

Works great. You have to wire it with good components to have it last a few seasons on a boat.
