Firenza 2300
Temp gauge clock working as when I short the sender wire out the gauge needle goes to hot.
I have changed the sensor unit for three others -- still no joy
I have tried warming the sender disconnected from the engine and connected to the sender wire - no joy
Strangely when I switch on the ignition but do not start the car the needle does crawl to Cold??
So - what voltage should I be getting at the end of the sender wire which connects to the sender unit ? mine seems to fluctuate -- is that normal?
