66 valiant gauges

The 66 american valiant has the IVR on the back of the gauge cluster pull the instrument cluster and there is a rectangular box that plugs into the board on the back. I highly recommend you buy an electronic one to replace the original one. (search on ebay for instrument voltage regulator) It is also possible you burned out the gauges buy having the IVR fail if they don't work after you replace the IVR test by shorting the sender wires to ground (very briefly) and see if the gauge moves toward the full or hot .
