If all your warning lights are flashing and the gauges drop to zero, it may indicate a serious electrical issue, such as a failing battery, bad alternator, or loose connections. First, check the battery terminals for corrosion or looseness. If they appear fine, consider jump-starting the vehicle; if it starts, have the alternator tested. If the problem persists, it's best to consult a professional mechanic for a thorough diagnosis.
they dont work
i had the exact same problem with our 91 voyager, i cleaned the battery terminals and the problem went away immediately
It means that you have a low reading on one of the gauges and you need to address the problem.
Usually when the gauges jump around there is some kind of computer problem. Your problem can lie in the body control module or in the ECM. Without looking at it, that is a tough call. The instrument cluster could be bad too. Those are the things I would check first.
The check gauges light comes on when one of the gauges is not in the safe range.
You may need to have the "Body Control Module" replaced on your car. We have a 2002 Saturn L200 and the same symptoms occured. Dash lights were flashing, dome light flashing, couldn't shift out of park, etc. Dealer replaced the part under warranty (at the time) and we haven't had the problem since.
There is no reset for a check gauges light. If the light is on, there is a problem either with the temperature oil pressure or voltage.

Posible relay problem
Usually around 220.
In a 1980 Jeep CJ5, the instrument voltage regulator is typically located on the back of the instrument cluster. It's a small rectangular component that regulates the voltage sent to the gauges. To access it, you’ll need to remove the instrument cluster from the dashboard. If you're experiencing issues, you may need to replace the regulator to resolve the pegging problem with the gauges.
