gauges just quit

i just bought a 1st gen teg and i was driving it home and my gas guage and temp gauge just dropped dont even know where to start to fix it the car has no fuses for either so plase help!!!!

check fuses

it does not have fuses for the temp gauge or the fuel guage.

check grounds. check the back of the guage cluster. soldering that looks bad. check the fuses for the guage cluster.
