I have a quick question regarding the Jaeger temp gauge in my recently acquired '62 TR4. The car has sat for at least 15 years and I recently got it started again. Within minutes of starting, the temp gauge shoots to 250 degrees and stays there. I didn't believe the readings, so I set up an experiment - I put the sender in a pot of hot water on the stove and wired up the gauge to a 12V power supply. I used two different meat thermometers in the water as a control and found that my suspicions were correct - it's way off. I guess the cheapest route would be to swap the sender and see if that fixes it but I'm curious about the reliability of these temp gauges. Anyone have any feedback on whether I should start searching for a new gauge, too?
Here are some pics. With the water temp at about 170, the gauge is a needle-width below 250!
