Lost electrics in '86 300E....

[865sp300e]

...but thanks to this forum the problem was quickly fixed.

My 1986 300E slowly lost all power while on a interstate at night. First the antilock warning light came on, then the radio lost power, lights began to dim, and eventually the car died.

A search in this forum suggested the voltage regulator and after following the diagnostics it was confirmed to be the culprit. The local auto parts store had the part ($35) and it took me about five minutes to replace.

The pictures indicate the worn brushes, only one of them was making contact.

Thanks to expertise in this forum for a fast, easy, and inexpensive repair.
