Gauge Circuit Board/Gauge Issues

[64lonske]

1964 Dodge Polara 500. I pulled my gauge cluster as the temp gauge was not working. Turns out there was corrosion on one of the poles. I ordered a new temp gauge and decided to update the gauge circuit board, voltage limiter, the plug/twist light bulb sockets and the bulbs. Problem....Fire up the car all gauges work or seem to be working. Gas gauges reads correct, oil pressure were it should be. Let it idle for a 5-10 minutes or drive away and the gauges slowly go to very low or zero. Then they kind of fluctuate from zero to low, but never come back to what I would call a live/accurate reading. I have not started to test anything yet as I'm looking for some advice before I get to far down any rabbit holes. I'll pull the gauge cluster back out this weekend. Thanks in advance.

Maybe IVR. Could be solder or Revit connection.

Local Napa here sent the entire stock of IVR back to supplier due to chinesium.

See rt-eng.com

Where did you get the new circuit boards? I had problems with my old circuitboards, and found this place in Canada called Mr. Heaterbox, their boards are really robust.

Classic Industries. Here is the link for the one I ordered and installed. Nice product:
