Problem Description and Possible Solution
The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.

Insulation on wiring harness degraded and disintegrated. Initial estimates include $800.00 for wiring harness replacement parts from Mercedes, and over $1250.00 for installation by the most reasonably priced independent auto electrical shop I could find in San Diego.
