DIAGNOSIS: The scooter is receiving zero power. The most likely cause is a drained or incorrectly seated main battery.
FIX: First, ensure both batteries are charged. Check the LED indicators on each battery pack. If either shows low or no lights, charge it separately with the provided charger. Second, physically remove and re-seat both batteries. Push each one firmly into its compartment until you hear a distinct click, ensuring the locking lever is fully engaged.
IF THAT DIDN'T WORK: The issue may be the power switch or its internal wiring. Confirm the scooter's physical power switch on the deck is in the ON position. Listen for a very faint click when toggling it.
HEADS UP: Always turn the scooter's power OFF via the deck switch before removing or inserting batteries to prevent potential sparking or controller damage.
