my outside temp gauge was working fine yesterday. Last night I was trying to diagnose a whining sound from my engine which I think is the alternator. So i was turning the headlights on and off to change the load. Anyway this morning all the presets on my radio are gone and the digital temp gauge was reading about 90 when it's 50 outside. How the heck do i fix this? What happened? Any ideas or help please. Thanks.
 






Ok weird. I let it sit an hour and now I think it's reading right. Where does the gauge get it's signal from?
