After initial install #3337 worked properly, reading 180*. During a single 4 hour drive needle gradually fell to zero. I found & fixed a loose ground, still not working. If I remove the ground completely then the needle recovers to proper temp of 180*Thank you for reaching out to us. This may require some additional dialogue with our Technical Support Team. A couple things to check; on the back of the gauge there are 3 small nuts that create the connection between the terminals and the actual meter movement. Make sure those nuts are not loose and also ensure that nothing is touching or shorted between that very small area on the back of the gauge where everything connects. Also, keep in mind that sender must create a ground through the threads of the sender. If an excessive amount of sealant or Teflon tape is used, that can prevent a good ground which can negatively affect how the gauge reads.

The needle is no longer registering on the gauge and is grounded to the same block as the volt meter which works fine. Do you have a replacement sensor available for the 3337?Hi Chad, thank you so much for contacting us. Most commonly, when a gauge like this reads low or not at all, it's because the sending unit lacks a good path to ground. Make sure the sending unit is free from any teflon tape which can keep it from registering. If it's remotely mounted (ie not directly mounted to the engine), you'll want to make sure you're providing an auxiliary ground to the body of the sender or the adapter that's being used. If none of that corrects it, I would recommend testing the gauge before buying any replacement pieces. With the gauge powered up and the sending wire removed from the sender, the gauge should read all the way cold. If you then touch that sending wire to ground, it should peg all the way hot. If that happens, the gauge is most likely perfectly fine and you mat want to try a replacement sender: https://www.autometer.com/short-sweep-electric-temp-gauge-sender-250-300-and-340-deg.html Hope this helps!Date published: 2018-06-25
Is this Gauge MechanicalHi Dick, thank you for reaching out to us. The 3337 is electric. The comparable mechanical version would be either model 3331 (280 degrees) or 3332 (240 degrees).Date published: 2018-05-04
Wat wire do you use on the back of the gauge to the sensor, didn't come with one
