Hello fellow Alfa owners, i'm opening this thread hoping you could help me with a problem i recently started having on my Alfa 156 1.8 TS '99.
Few days ago, my battery was getting weaker. Few times i've required a friend with jumper cables to start the car. I was thinking it was time to replace the battery but today's experience had me buzzed. On my way back home, car started stalling so i've pulled over for a bit with engine still on. Turned off radio and lights and tried revving it a bit. It seemed fine so i've kept going but once i turn on the lights, car stalls again. I've managed to get home without lights and started troubleshooting the battery. It was empty and couldn't start the car. After recharging it with a charger, car started but it looks like alternator is not charging.
While engine is running, if i disconnect one of two connectors from the battery, car dies. From previous experience with cars, that is the sign of failed alternator. Interesting thing is that the battery indicator on the dashboard is working as it is supposed. When in ignition, battery light is on. As soon as engine is started, light goes off as it should.
I've searched the forums but couldn't find a thread with same symptoms (dashboard light not showing the error). I've connected it to the diagnostics software, and only fault found was 'Battery voltage'.
I really hope there is some easier fix for this other than replacing the alternator. Judging by the threads i've read so far, it's 'painful' to change and requires tearing down half the car.
