(EP876701-A1)      The wiring for a voltage regulator in the car's power loom has a main wire (6) connected directly to the battery and an auxiliary wire (9) going to the ignition switch. The regulator has one output, a power input from the main wire via a diode and a signal input via the auxiliary wire.    The auxiliary wire is also joined to the main wire by a second diode (10) and has a buffer condenser (12) between it and earth. The power input to the regulator has no such condenser connected. The diode joined to the auxiliary wire prevents the condenser from discharging. The signal input has a fuse (15).    ADVANTAGE -   With voltage sags on either main or auxiliary wire, regulator remains active as long as possible to supply constant voltage to circuitry following.
