RE: alternators and relays-Mark Kinsler
- Mark, I believe it is too conventional to say that Alternator is used
EXCLUSIVELY to charge a battery.
When we discuss the function of automotive alternator, it must be in the
engine running contex. In this situation, ALL regular consumption of
electricity is provided by the Alternator, including the replenishment of
those consumption from the battery during engine off and during engine
When we use the conventional understanding, we might be in trouble adding
an-Ampere meter in our car.
During engine off, all the electricity are provided by the battery, but once
the engine runs, the alternator takes-over that task. The battery is then
functioning as: 1) Auxiliary (?) for transient electricity loads such as
turn signals, horns and brake lamps; 2) Part of Alternator's load,
especially during current replenishment.
