Re: Charging System Light
I don't know about this smart alternator.
Since the charging update I have been monitoring the voltage while driving.
I am only seeing .2v deviation. 14.2v to 14.4v using a OBDII monitor.
If it was to go into a no charge state say under full acceleration the voltage should drop.
I tried this yesterday after the car was sitting for most of the day in the sun fridge running of the second battery takes about an hour to get it back to charged state. and charges at the same time as the car battery. So we got a full load on the alternator. Under full acceleration voltage did not change.
4 hours later running at 110kmh for that time. Tried again no variation.
My conclusion is the alternator will charge when it sees the battery needs it and floats at 14.4v. and will maintain that up hill down hill full acceleration full engine braking. After all we are not driving a hybrid.
Stop your car and just turn on the ignition check the voltage it will drop rather fast to 12.6v and then hold there.
If the alternator was to go into a non charge state or limp mode I would expect to see 13.8 volts or lower, but this has not been the state.
