An energization control apparatus includes a control portion, a disconnection detecting portion, and a prohibiting portion. The control portion controls energization to a plurality of loads coupled in parallel. The disconnection detecting portion repeatedly or continuously determines whether a supply current to the plurality of loads is less than a threshold value when the control portion energizes the plurality of loads, and the disconnection detecting portion detects a disconnection of a part of the plurality of loads when the supply current is less than the threshold value. The prohibiting portion prohibits a disconnection detection by the disconnection detecting portion for a predetermined period since the control portion starts to energize the plurality of loads, and the prohibiting portion enables the disconnection detection by the disconnection detecting portion after the predetermined period elapses.

Energization control apparatus

A meter system includes: an indicator including a pointer, a step motor, a stopper mechanism and a driving controller; and a flasher function unit including a flasher switch, a flasher and a flasher controller. The driving controller has: a stopper position detection operation executing element for executing a pointer moving away operation when a stopper position detection operation executing condition is satisfied and for executing a voltage detection type zero point stopper position detection operation when the executing condition is satisfied, and the flasher switch does not turn on and off, and a zero point return enforcement type zero point stopper position detection operation when the executing condition is satisfied, and the flasher switch turns on and off; a zero point setting element; and an applying element for applying the driving signal having the zero point.
