Reply to "Chuff Generator Install Help"

Hrm... Not sure what to try next. I know the 5 volt board is putting out the correct voltage. Verified the positive lead is connected to the positive lead on the Chuff board. Verified I am using the correct pin off the motherboard chuff connection to the chuff board. I retried the LED test with a flashing LED to ensure the DC power coming from the 5 volt board is filtered. I know from a prior upgrade that flashing LEDs do not work with half wave DC. The LED flashed, so I know the DC power coming in is good. When its all connected the red light on the chuff board lights up and never goes off. I could try and put the old motor driver back in and I could trace the chuff connection on the motherboard and see where it goes.

So based on the LED testing, the chuff board defaults to a ground connection and interrupts the connection for the chuff. And this was suppose to be a simple upgrade...
