lard44 0 Posted February 23, 2013 Hi all, Got around to installing my breaker-sourced ambient temp sensor today, only to find that it's reading either + or -40 degrees. It's cold out, but not that cold... So I'm trying to trace whether this is a wiring or sensor issue - I have a multimeter, what sort of resistance should I be looking for across the sensor?
