Just trying to confirm that the alternator on my 98 ls has died. Charging voltage with lights and ac on was at 9.8 at idle, went up to mid 13s at around 3000 rpm. The charge indicator comes on only when the voltage drops below 9.8. With the lights off, ac on voltage is at 11.5. The car has 124k miles, and no PS leaks. I replaced the PS pump last year, because it was noisy, but not leaking. The battery is OEM and a year old. I also got the VSC indicator yesterday while stopped at a light, which prompted me to check the charging system.
Voltage on my 735i was at 13.6 at the same conditions as above.
So this leads me to believe that the alternator has died.
