My beloved '93 300SD (Big Mamma) is operating perfectly, but has begun flashing some or all of the idiot lights in her dash from time to time while under way. Any ideas?

Intermittent electrical problems are quite difficult to diagnose in person, and almost impossible via a forum.

Ususally the problem has to become steady so that you can trace it down, or it has to become so predictable that you can make a temporary alteration to duplicate the problem, or prevent it.

Some questions you would need to ask yourself, and observe the answers.

Is the Battery Light always involved?

Do they flash in a regular pattern, or in a random pattern and then go off?

Do some/all flash fully-bright, or dim?

Are there any that do, or do not flash consistently?

Please observe some more and give us more details so that we might be able to help.

Best Regards,

Flashing lights are random and never the same light first. Sometimes includes the battery light, but not all. Pretty tough to figure out..

Thks much
