I still had the original mechanical voltage regulator in my car's alternator. It was working but not correctly; recently, the voltage reached 15 volts, which is unacceptable. On drom.ruin the retro section, kind people suggested that I could adjust it by bending the spring plates, and this worked eventually to achieve 14 volts at idle speed, though the voltage fluctuated under load.

What's inside the regulator?

it's installed on the car

and from another side

I decided to solve this problem because the original regulator is very expensive. Replacing it wasn't an option as catalogs didn't offer alternatives. My friend from a generator service suggested an electronic replacement which costs only 1300, or could be bought for 1000 with longer delivery time.

The voltage is now normal and stable

It looks much better this way

Next on my list are lambda sensor and msc replacements. While I understand how to install a universal lambda sensor with minor adjustments, changing the msc without removing the cylinder head would be surprising. This is not what I want.
