I got this input from Steve the designer of the Steve converter. Evidently the Steve has a high input impedance and may need a pull down when connected to an open drain off a P channel FET like the mCP X + motor output. Tnt you may want to add a resistor or just connect the yellow wire to the IC output at the resistor like Jon did as it is an active signal with fairly low impedance. Steve also said that the mCP X has some voltage sensing circuitry that may need the pull down resistor to work correctly.

Once again just because it works doesn't mean it is right (an old saying of mine)

Good looking out :-)

I added a 2.2k ohm resistor 1/4 Watt 5% tolerance to my set up. I solder one end to the yellow wire of the steve converter and the other end to the blue wire of the Steve converter. Here are some pics

Have a blessed week
