ABSTRACT:
A test circuit for automotive voltage regulators includes means for simulating transient battery voltages, a meter for monitoring these voltages as related to the operation of the regulator being tested, switching means to protect the meter and also to facilitate the reading thereof, a test load simulating the field coil of an automotive alternator, and an indicator light for determining when the test load is energized. The volt meter indicator moves to show increasing voltage and returns to zero when the regulator interrupts the current to the test load.
