Hyundai Tucson: Starting System- Description
The starting system includes the battery, starter, solenoid switch, ignition switch, 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.

The battery must be in good condition and fully charged for this troubleshooting
