I am terrible when it comes to electrical troubleshooting.

My coolant gauge is not registering. I have taken the plug off at the engine water bridge and ground the blue wire and the gauge will register hot. I then ground the brown and the alarm light will light on the gauge. I tested the resistance between each terminal blades of the sensor to ground. Nothing registers on the meter. When I put the plug back on the sensor the gauge will not work.

I have also replaced the sensor.

I hope I explained my problem well enough.

Thanks. Mike P
