Ecosport Overvoltage Faults

I'm getting many fault memory entries relating to overvoltage on my 2015 Ford Ecosport diesel, and various systems are failing. I've also noticed the battery seems weak when starting, and there's a general electrical malfunction. Could a heavily discharged or defective battery really cause this?

Overvoltage... Isn't that usually an alternator issue? I had similar electrical gremlins with my old Opel Astra a few years back. Did you check the voltage regulator?

The voltage regulator... Is that part of the alternator, or is it a separate unit? And would that cause all those symptoms?

Yes, it is usually part of the alternator. And in my case, it caused a cascade of electrical problems. I'd suggest getting it checked at a workshop; they can diagnose it properly.

Thank you for the insights. It turned out to be a defective alternator. The repair, including a new alternator and labor, cost 290€. Your advice helped me point the workshop in the right direction!
