Alternator voltage
Looks like this may have died. I have a, 2010, Chevy Cobalt. I have never liked the High Battery Voltage of 15 volts. I also believe in the lights on 24/7, safety. I have heard about a Smart Alternator. Some ideas seem good, but they may have off-shoots that are not expected.
If the alternator put out a regulated 13.8 V. As the battery reached charge, the current should drop off, as apposed to a Constant Current, which the battery would have to absorb and give off as heat, and possibly boil or "gas".
I used to drop the battery to the headlights with a 6A diode in the ground lead, to reduce the Lamp voltage, and increase the life. Have been thinking of putting in TWO in series to reduce the voltage by 1.4 volts. 0.7 volts drop on each diode.
I find it hard to see a real advantage to varying the Alt Volts.
I CAN understand an advantage between the Ears, behind the eyes.
