69 with gas guage and interior light problem

I just got my first 69 camaro and it is in great shape. Only problems are the gas guage is on empty all the time, and the dash lights will go completely out when im driving sometimes and if i tap the light switch on the dash they will come back on. Any helpful hints would be much appreciated. Thanks, Darren

Re: 69 with gas guage and interior light problem

Reach up and grab the headlamp switch. Twist the bejesus out of it. Turn on dash lights and rotate knob to vary brightness.

If lights flicker, return to twisting the bejesus about knob. If dash lights don't flicker, job done. What happens is the potentiometer wiper, a carbon contact, gets buildup upon it. By twisting the knob vigorously, you remove the buildup. Usually, a monthly preventative maintainence event.

As far as the fuel gauge goes, in the trunk by the latch, you will see a connector with a brown wire. Disconnect the connector and turn on the gauge, it should read way past FULL. If gauge passes last test, gauge is fine.

With disconnected connector at trunk floor, use an ohmmeter and check the resistance of the brown wire going out the floor, which goes to the tank sending unit, to a good ground. Hopefully, it will measure something between 0-90 ohms. If not, either the black wire screwed to ground at the tank retainer is broken or not making good contact to ground, or thew sending unit is bad, or a float that doesn't float anymore. Floats can be bought indivdually at the specialty gauge/speedo repair shops.
