Motor Controller 2.0

[SYWindveer]

Try connecting a pair of LED's with 10K series resistor to the motor output. ( without the actuator)
You should see the LED's switch on depending on direction

If this works your actuator may be defective or the power supply can't provide enough current.
You may want to try a boat or car battery instead

My problem isn't anything to do with lack of current or a defective actuator. My problem is with the motor controller. I cant connect it to the psu (with or without the actuator) without the psu shorting.

If you bought the controller then contact Sean.
The controller is protected against reverse polarity and with a fuse.
I assume that if there is a hard short the fuse would blow.


If you have a multimeter, check for a short over the supply terminals, check the motor terminals too.
Low resistance is not good.

You don't say what power supply you are using, some are protected against overcurrent and will shut down.
Did you check the actuator directly on the power supply  does it move ?
