FAQ Category: Water Temperature

My new water temp gauge seems to show temperature changes more than my old one. Why?

The needle moves in reaction to the signals it gets via the PCB from the water temperature sender.  It is most likely just more sensitive than your old one and it shows as needle movement.  If you believe your water temp is constant and the needle is moving it is most likely a wiring connection interfering with the signal from the sender or from the PCB.
