temp & oil gauge not working
Ok so you still have the originals in the cluster? Mine are aftermarket replacements that are almost just like the originals. Assuming no one has messed with the original wiring or modified the 5v regulator in the fuel gauge then Chances are they looked like my originals and were toasted. Oil pressure was always 80 or more and temp was always around 220 or more. Likely they are bad. If your fuel gauge still functions well then the built in regulator is likely still functional or at least marginal. Explains the pulsing you see. Sounds just like what my 69 was doing. I would recommend what I did and replace them with the upgraded original style looking units if that is what you want. I did not want aftermarket gauges under the dash or wherever and wanted the cluster to work great. Here is my what my original OP and Temp gauges looked like inside. No wonder they were inacurate. My fuel gauge nichrome was still nice and white colored.
