Lexus SC300 / Lexus SC400. Manual — part 284
DESCRIPTION
The alternator is a small, high–rpm, high–performance type with an IC regulator incorporated. The IC regula-
tor uses integrated circuits and controls the voltage produced by the alternator.
PRECAUTIONS
1.
Check that the battery cables are connected to the correct terminals.
2.
Disconnect the battery cables when the battery is given a quick charge.
3.
Do not perform tests with a high voltage insulation resistance tester.
4.
Never disconnect the battery when the engine is running.

Description, Precautions
SYSTEM CIRCUIT
OPERATION
When the ignition switch is turned ON, current from the battery flows from terminal L of the alternator through
the IC regulator to terminal E, causing the discharge warning light to light up.
Then when the engine is started, the voltage output increases as the alternator rpm increases. When the
voltage output becomes greater than the battery voltage, current for recharging flows from terminal B. Simulta-
neously, voltage at terminal L increases and the potential difference between battery and terminal L disappears,
causing the discharge warning light to go off. When the voltage output exceeds the regulator adjustment volt-
age, the transistor inside the IC regulator regulates the voltage so that the voltage from the alternator remains
constant.
