Why does my Oshan X7 experience dimming headlights and slow electrical response at low RPMs?

When driving at low speed o r idling, the headlights dim slightly, and the infotainment system lags. Could this be related to a weak alternator o r voltage regulator problem?

Dimming lights o r slow infotainment can be caused by:

A weak alternator that cant maintain proper voltage at low RPMs.

A failing voltage regulator, which doesn’t adjust current output correctly.

Battery nearing end-of-life, unable to support voltage dips.

Corroded wiring o r ground points, reducing voltage delivery.

Diagnosis:

Measure voltage at idle and while revving should rise to ~14V.

If the lights brighten when accelerating, the alternator isn’t keeping up at idle.

Have your alternator and battery tested together at a service center.
