(65 coupe) My fuel gauge and temp gauge don't work. I'm only reading about 4 -6 volts on one side of my constant voltage regulator (the side coming in from the ignition switch) and 0 volts on the other side. I was thinking I would read 12V on one side and then some regulated voltage at the output side. What should I read and how do I interpret the readings I have? Thanks in advance.
