[QUOTE=DeluxeOKC;12462961]Final update: Problem solved. As I suspected in my last post, it was indeed the alternator. I bought a Bosch reman (from O'Reilly of all places) for $139, and had it swapped out in under 30 minutes. Voila. All of my idiot lights are back to normal function, and I'm seeing 14.35V at the battery at idle.
this high voltage is scary. I am afraid you get wrong alternator. Just for sure, please check the parts number of voltage regulator ( with mirror it is easy )
For E320sedan 1 197 311 213 (Bosch) is a right one. (MB number: 002 154 8506) For Wagon 1 197 311 242... This is a common mistake of US parts suppliers, they don,t know right about E320 models....
Using another regulator or alternator is not a joke, this could follow several damages in the system. 14,5 V is a highest possible voltage - this is when the Battery fully (over?) charged.
Please check the battery Voltage ignition of. Normal around 12,65. Start engine and check the voltage in idle ( A/C, Light, rear window heater on) Charging in this case around 13,65 V.
Please note: OVP relay will abuse with the high voltage. Your OVP is already done, tired, .
