Question about 1993 Dodge Dynasty

1 Answer

Gauges go Wild when Headlights are Turned on

When my 93 dodge dynasty is running and I pull the headlights on, the gauges go wild. Then, if I turn on the turn signal, one gauge actually clicks up and down in unison with the signal. I'm assuming it's a short and have looked for broken wires...can't find anything though. Any advice?

    I did remove the instrument cluster, but I can't pull it out far enough to see anything (wires are too tight). I reached inside the hood and jostled a large cluster of wires. After that, the short seemed to be gone, everything worked fine. I'd still like to figure out where the short is so I can repair it of course.

The back side has a circuit board which sound s like a short has occured. To inspect this problem a dark burnt area will be present if you had removed the instrument cluster out to see. The circuit board is like a soft floppy plastic sheet with the copper circuit embedded inside of it

I have a 1983 Chevy S10 pickup. With headlights off all gauges work normal. When you pull the headlight switch on all the panel lights except the windshield wiper switch locator light never turn on and all...

take a look at the dash ground wire located next to the right of ebrake release handle. if the bole holding the ground wire is loose, which was quite common it will cause all kinds of feed back problems, like described in the comments section to your question.

Taillights wont burn

You'll have to use a 12vdc test light and start probing for power with tailights on, and I'd work from tailight & go forward. You did check all your fuses right?

Gauges turning off


  1. I would seem that your electrical system needs a thorough look over. Suspect would be connectors (either corroded, loose or burned), fuses and relays. Specifically:
  2. windows don't go down - check the fuse, switch motor;
  3. the gauges all turn off when the brakes are pushes - check that the gauges IGN B+12 is not intermittent (loose connector from IGN switch);
  4. the gauges turn off then back on when the headlights are turned on - same probable cause (loose IGN B+12);
  5. the brake lights don't work - faulty brake switch, burned out bulbs, loose/no +12 sup[ply to switch.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
