Need help finding new temperature gauge

Some things to do.

1.....Look up the destructions for your multimeter, and see if there's a special setting for low resistance measurements. Or post the brand and model here

2......Take your meter and place one probe onto each of the harness connector pins, with the other probe stabbed into the copper trace on the board which hooks to it. Wiggle the pins and see if the resistance changes or that there's any physical movement. Best plan is to clean them and solder them from the pin to the copper.

3.....See the screw immediately to the left of the VR? That screw, and any other screw which screws into the cluster and which goes through copper on the board is a ground, but there's nothing to ground the cluster "for certain" to the car. Hook a pigtail wire to that screw long enough that you can bolt it to the column support before you finally insert the cluster.

4.....Pull the VR out. You'll see those brass contacts which act as the VR "socket." Those MAY NOT be making good contact with the board traces!!!! Solder them across. Check with your ohmeter

5....Notice the fake nuts on the studs of the gauges. These may not be making good contact. Loosen/ tighten them several times to scrub the connection clean. A better plan is to replace with real nuts. Do not overtighten.

If you look at the PC board, you can SEE where every circuit goes

For example, look at the trace coming off the lower right of the VR which goes to the right hand stud on one gauge, and the left hand stud of the other. This is the regulated output of the VR. The remaining studs of the two gauges go by PC trace up to the respective pins of the harness connectors and off to the temp and fuel senders

My poor edit shows the screw which is ground, and the circled area is power output of the VR going to the gauges
