Temperature guage Options

[Montreal914]

Hello everyone, after being on the 914 club for almost a year, I finally decided to join the 914 world. I don't know what the story is but there has to be something in common here, other than the main topic of course... (IMG:style_emoticons/default/idea.gif)

Now to the main subject. I was driving on the highway at about 70-75mph for about a half hour yesterday and this is what my temperature gauge was showing. The outside temperature was about 80-85 SoCal.

As a matter of fact, the guage takes the longest time to get up. So, I guess there is only two things that can be wrong, the guage or the sensor in the taco plate. Is there a simple way to verify them? Is there some measurement that I can do with a standard voltmeter?

Thank you

Also remember that the temp travel is shorter on the wide-red-band temp guage - as opposed to the later ones with the short red zone. IIRC the red zone on yours starts at about 450 deg., so divide up about 60% of the gauge arc & I agree with avidfanjpl/John above - you're about right for a 80 degree SoCal drive.
