My temperature gauge is not working!
If you have just installed the gauge, ensure you are using the sensor provided as other sensors will not work.
If the gauge does not sweep on startup, it is not getting power. Verify the red, white, black power harness is connected properly.
If it sweeps but is not reading at all, ensure the signal harness is connected and pressed in firmly on both sides.
If it's still not working, test the signal harness for continuity with a multimeter. If you have both probes on the metal terminal and it reads "OL" or 0 ohms, the harness is bad. Call or email us to get a replacement harness. You can put paperclips in the harness connector if needed to get a good contact point.
If the harness is testing good, the next step is to measure ohms coming from the sensor while it is warm. Refer to the chart below, if the ohm reading is close to 0 or it's an OL, you need a new sensor. We recommend reading the ohms at the gauge side to verify it is getting to the gauge.
