GAUGE PROBLEM WITH HIGH BEAMS

When I turn on my high beam lights or my turn signals my fuel and temp gauge quit working and go all the way to the right side of the gauge. I also do not have any lights working in the cluster for the gauges. I checked and the grounds are tight, I replaced the high beam foot switch and still have the same thing going on .HELP.

This must be a typical FSJ item. When I turn my head lights on, my oil presure guage drops and my alt meter drops and when I go over bumps, the bounce along with me.

Sounds like a wire is crossed, obviously.

I had this problem on a Saab. Turn the hazards on and the fuel gauge would bounce and the right blinker made the temp gauge bounce.

Changed out the instrument cluster and all was well. I think the foil got shorted out in the back somehow.

Also my best suggestion ... pull the whole cluster and tear into it. I'll bet you find that the foil has been tweaked. Good luck

89 for me.

last night i reached up behind the dash and pulled some of the bulb sockets out of the back of the gauge cluster. the bulbs looked fine, but none worked. so i guess it might be in the cluster or the wiring. i was just wondering if there was a known problem similar to a "technical service bulletin" about that.

It is the headlight switch or your dimmer switch.

Check the voltage sensing wire on the alt. If your voltage drops, then it will throw off the gauges as they are calibrated to work at about 14v. If you have any charging problems, the extra load is creating a voltage drop in the system and the gauges quit. I had that problem on my CJ until I cleaned up the wiring for the alternator.

i'll look into the alternator wiring, as i can see that making sense. but here's what throws me off. my guages don't go "down" when i turn the light on. they go "up". the coolant temp gauge, and fuel gauge go way past full/hot.
