I have a 1974 2+2 that only seems to have the clock working and nothing else. The temperature, oil pressure and fuel gauge do not work and I am not sure about the amp gauge (it jumps a little when Ignition is switched on).
The tacho, likely unrelated just goes to fuel gauge deflection when the ignition is switched on.
Is there a voltage regulator or something that will take all the gauges out?
Any help would be appreciated
