Moved my 68 charger around a couple of times recently when suddenly temp and fuel gauges dropped to nothing. Oil and alternator gauges are working fine. That they failed together makes me believe it has nothing to do with the senders. What could cause this? Thanks!

Alternator gauge is completely separate from the other 3. Could be a circuit board issue or a grounding issue. With the key on you could momentarily ground the wire for the temp gauge and see if the gauge needle moves. It should move towards hot side pretty quickly. Don’t ground it for very long, only a few seconds to see if the gauge needle moves.
