You said you measured 13.8 V ... was that with the engine on or off? I'd guess the engine was on so that indicates that the alternator is fine......you could switch everything electrical you can think of on.....if the voltage doesn't drop then the alternator is fine.
What makes you think you have a problem?
I just came from a battery testing place and i got the same voltages as before.13.8 v when engine running and nothing on.13.6v when the main beam was fully on.The owner said that its on the border line.Which means its ok but pointed out that a car with a lot of electrical stuff should be 14v.The battery will be a year next month.It was also tested with a volt metre and read 12.56v and they also used a tube like device which tests the liquid charging capacity and it read fair.
I could have a problem because sometimes when closing the windows they move slowly and somewhat get stuck then continue to close.
I will taking the car for service at end of next month.All autoelectricians, i have taken the car to have no experience in removing an Alfa alternator to have a look at it.They keep refering me to the dealer for removing the alternator, but there no longer is an agent in my country.They can do minor service but i dont want them messing with my car on major jobs(they could make it worse)
I will take to South Africa 350km, relatively good alfa agents.In Southern Africa the battery voltage is said range between 13.6v to 14.2v anything above is said to be over charging.Then again i have a selespeed.
How will this affect, the lifespan of my 10 months actuator, pump(5 yrs) and other expensive bits?This is, if i have a problem at hand.
