With my TPS hooked up and plugged it, my battery voltage shifts with my TPS on TS, but when I unplug the TPS my voltage is correct.
My TPS is wired correctly, and seems to be functional at least. The ground for it is direct from the UA4C, and the 5v Ref pin is only being used my the TPS.
Essentially what's happening is that with it at 0 throttle, in TS it will show my battery voltage at 8 volts even though I'm holding 13.9 easily, and the voltage will go up with the tps, for example 17V with the TPS maxed out. I'm not sure what kind of problem I'm dealing with and any ideas would be fantastic.
Am I dealing with a bad board or arduino? Or do I have a bad TPS. Or is there something else going on
