Driving a 1.8 TS (111000 km).
The battery icon starts/stays (slightely) lighted after I turn the engine on, then fades slowly off in less than a minute.
Measuring the battery voltage, engine off: 12.40 V. When the engine is on: no more than 12.80 V!
I guess it should be around 14 Volts.
I changed the battery 6 months ago!
On the alternator side, the Vcc output connector gets quite warm. Normal?
If it's the alternator:
Does the alternator can be fixed or should it be completely replaced?
It's behind the engine. Can I change that, or open it to check the electronics, diodes inside? Or something not worthy to do, too dificult (distribution belt stuff tricky), and better go to a car (electrics) specialist/garage?
Could it be another alectric part damaged between the alternator and the battery?
