Another temp sender/temp gauge thread
I did a search, read through what seemed like hundreds of temp threads and tested my sender before posting this. I have a new temp sender and an original gauge. I tested the new sender in a pot of boiling water and got a reading of 95 ohms which I believe should make the gauge read low correct? I then put the sender in the boiling water and hooked it up to the gauge and got a reading over 200 (pic attached). If my thinking is correct doesn't that mean my gauge is reading high? Your input is appreciated. TIA

Here is a good thread....
from this forum. Notice that I actually bought a different new 3/8" sender and it reads the same as my original that I placed in the intake manifold. They both read low, and I know that because I'm running EZ-EFI 2.0 which monitors temperature and give me a digital reading.
I think my temp gauge is off ..... one of these days I'll get the Wilcox (temp gauge adjustment contraption) to check the performance of my temp gauge.
Below is the wilcox page for their gauge adjustment unit:

Meanwhile take a look at this thread:

What year is the car?
In the picture below you'll see the required inputs for the 1979 temperature gauge. These readings are what we use to calibrate a dash unit to the factory settings with a stock resistor. However the required input can vary from gauge to gauge based on the condition of the gauge.

Interesting observation....the 78 gauge reads 200 degrees at 12 O'Clock, 79 gauge reads 220 degrees at the 12 o'Clock position (78/79 L-82's ran hotter than Hades) and the 80-82 gauge goes back to 200 degrees at the 11 O'Clock position on the dial with the 12 O'Clock hash mark probably representing 220 degrees. The 78/79 L-82's and probably the very few 80 L-82's routinely ran 225 degrees without AC running causing panicked customers of those cars to question GM on the high temps.
