Sorry dude... not enough info here to make any helpful ideas.

You need error codes or something more helpful. 14 some volts when engine running is normal.

From what you have described, one cannot definitely say that the voltage regulator is faulty. Nothing wrong with 15 volts charging the battery, depending on its state and type. And 14 volts resting is also normal. Sometimes "a little knowledge is a dangerous thing".

as soon as auto electrician disconnected the plug from regulator charging voltage was normal and not had any problems with the car thats 5days now so might keep fekn thing now 😎😁
