Here is a possible answer to you blinking light issue in the form of trouble shooting and some advice.


To start:
1. Make sure you have a clear map (printed chart) of what wire goes where and controls what.
2. Lable every wire, every speed controller, every spike, including every PWM wire.

Blinkng light on speed controller usually means that it has power but a path of control is not right.
1. Review your map - is your PWM plugged into the port you say it is to be plugged in and is it matching your program?
2. Are you testing the right motor (is it plugged in).

Now here are several real possibilities.

1. The PWM wires are very sensitive to being plugged in backwards. They will not work. Check both ends.

2. Is the PWM seated fully - Hint! Look at the speed controller slot (deep in the slot) for the PWM receptical. It often gets pushed to one side and when you insert the PWM wire you are not in alignment with the pins.

3. Is there a small piece of plastic or other junk blocking the hole or holes?

4. This is really the first thing to do.... Sub in a known good speed controller and known good PWM wire and test.

Stop.... slow down.... use a logical trouble shooting process.

Do not blame the controller yet..... usually it is not the problem.
