Hyundai Sonata LF: Starting System / Starter Description and Operation
Hyundai Sonata LF 2014-2019 Service Manual / Engine Electrical System / Starting System / Starter Description and Operation
| Description |
The starting system includes the battery, starter, solenoid
switch, ignition switch, inhibitor switch (A/T), clutch pedal switch
(M/T), ignition lock switch, connection wires and the battery cable.
When the ignition key is turned to the start position, current flows and energizes the starter motor's solenoid coil.
The solenoid plunger and clutch shift lever are activated,
and the clutch pinion engages the ring gear.The contacts close and the
starter motor cranks.
In order to prevent damage caused by excessive rotation of
the starter armature when the engine starts, the clutch pinion gear
overruns.
In conjunction with the ISG function, the starter motor must
do a great deal more work. Therefore, the starter motor is configured
for a significantly higher number of start cycles. The components of the
starter motor have been adapted to the higher requirements.
