I'm leery of connecting anything to the accessories terminals until I get this resolved. Would hate to have the voltage jump from the current less than 1 volt to something higher than the 8 volts (the original setting if found before I first tried these instructions).
Later tonight going to try by connecting the track posts to my test track.
Also going to try by very slowly - and I mean very slowly - like 30 seconds - to raise the throttle. Previously I did it in 10 seconds - maybe that's too fast?
