Adjustable temp sensor

Long Island has an adjustable resistor for sending unit. 22-17c
Has anyone tried one?

Yes I have one on my 57. An accurate sender in like trying to find a unicorn. It's basically a resistor that sets the temp gauge at a known temp. I set mine at 170 degrees from taking a reading on the water neck with a temperature gun. I believe the reading is only good for the temp you set on the gauge. Mine works great.

Where did you wire it in? The write up for the unit talks about wiring it in under the dash

Yep, that's what I did. Easy access to the tiny adjustment screw on the unit.

Does the unit need to be near the temp gauge? Access is difficult on a C2 - the temp gauge is above the ignition switch. It would be much easier to wire it in under the hood

If its wired as a simple "series-connected" rheostat it could go in the temp sender wire from the unit wherever is convenient... Somebody would have to verify.

Interestingly - this is the same fix the factory came up with for the inaccurate temp sender reading on my Sea Ray boat...calibrated for accuracy at 170*..

I saw nothing magic about wiring it in under the dash, other than to hide it from detection. But I have been wrong before about stuff I didn't think mattered. Lots of time on this forum alone
