Re: Damage from no recirculation diode?

Well the issue convolutes further- I sustained a bit of a brain injury during the period after building this car and I have a new habit of forgetting things. I peeled into the harness and found a recirculation diode and a heat sunk resistor right where they belong although I can't remember doing it....

Thank you Lance. The first thing I checked (when the old code was still running) was the setup of the input lever configuration. It was and is still setup for GM digital switches. I even tried raising the digital voltage threshold from .9 to 1.9 to see if that would get the signals to go low. After ...

Damage from no recirculation diode?

I have built and installed a GPIO/megashift controller to a 4L60E and I neglected to install a recirculation diode and associated resistor in the pressure control solenoid circuit. After several tuning runs, the controller seems to have lost the ability to see the three input signals (switchA, switc...
