I have a 1968 Oldsmobile 98 and none of the gauges on it work. The speedometer doesn't work, gas gauge doesn't work, and my clock doesn't work. If anyone can help me with this that would be amazing. Priority one is to fix the gas gauge because I ran out of gas the other day.

Thank You.

 

Speedo is mechanical and runs off of a cable. On my 65 cable runs from speedo to left frount wheel dust cover. If clock is getting 12 volts it is most likely stuck. I removed mine, took cover off of back, sprayed with wd and it started working. The first question on fuel guage is it staying on full or empty. If on full, check for ground wire at sender.

 

first and easiest thing to check is the sending unit on the tank i think
