it's like xmas tree lites in series.
if the alt lite doesn't come on with the key in the ignition, car not running, the system won't charge.

if the light doesn't come on when the key is turned on, how will you know if the alternator fails.

i posted this a while back and it happened years ago in a volvo with a bosch ignition system, same thing.

no alt lite with key on, both systems showed a little over 12v when running, replaced the lite bulb in both cases and showed 13.7/8 after being started.

the volvo info came from a volvo service writer and he claimed it was one of the poorest designs he'd ever seen and golly gee, it's a bosch system in the p-car.

i'm used to checking lites when the system is powered up, silly lites like for oil pressure, generator + a few more and then making sure all of the lites are out as oil pressure/voltage come up before i go to work and before driving to work.
