GK76A water temp sensor resistance values
Posted: Fri Apr 16, 2021 9:28 pm
Hi all,
I start a new topic to submit a question regarding resistance values for the water temp sensor on GK76A 1991 (non SP).
I found that the water temp gauge is not going up really, just a few mm, even after 10km, and idle at crossing road, traffic light, etc.
So I decided to remove the water temp sensor and test the resistance according to temperature.
Here is a picture of the test:

The values I found are as follows:
30 °C => 625 ohms
40 °C => 390 ohms
50 °C => 255 ohms
60 °C => 165 ohms
70 °C => 112 ohms
80 °C => 80 ohms
85 °C => 67 ohms
90 °C => 56 ohms
95 °C => 47 ohms
> Do you think these values are wrong / right? Should I replace the water temp sensor? I could not find any documentation regarding this.
For instance, on FZR 400, I have these values from the manual:
153.9 ohms @ 50°C
47.5 - 52.8 ohms @ 80°C
29.2 - 29.3 ohms @ 100°C
16.1 ohms @ 120°C
BTW, I checked the gauge also and it goes to the maximum when I shortcut to the ground so it seems ok
Thanks for you help
