Hi everyone. I'm trying to build myself a simple remote fish feeder using a wingshield wiper motor. The motor has 4 wires: blue (slow speed), yellow (fast speed), pink (I think it brings the motor to home position) and a black wire (either for negative or I don't know what). I have two 12V - 8Amp transprmers. I'm trying to wire the motor so that when I remotely cut the power to one of the power supplies, the motor will return to home position. So far it will only do it if I connect the blue and pink wire but I can't use that as a solution. Can anyone help me?
