Re: Temp gauge works backwards
Attached pic of my 48 F1 gauges with the POWER OFF. Note the temp gauge position is HOT. Once the ignition is turned on it goes to COLD, and increase as the engine warms up. If you want to check the gauge calibration, disconnect the sender wire and connect it to a resistor of around 45 ohms (other side to ground). It will read around mid position in my experience.
