1978-83 Porsche 911- Low Output to No Output

As early as 1984, many 1978-83 Porsche 911s hit the emergency room with complaints ranging from low output to no output. After a thorough examination, Porsche determined that the location of the alternator in the engine compartment was the cause of apparent heat stroke. Since they could not redesign the layout of the engine compartment, Porsche prescribed a new voltage regulator which had aluminum cooling fins and two cable connections instead of one. This improved design helps the voltage regulator dissipate heat better and provides higher reliability. This remedy worked so well that Porsche made it a running production change in the 1984 and later models.
