Diagnosis
Main battery isn't delivering power. Could be a dead battery, blown fuse, or faulty main power connection.
How to Fix It
Check the internal fuse first. Remove the deck cover. Locate the battery fuse holder near the battery output terminals. Test or replace the 40A blade fuse.
If That Didn't Work
The Battery Management System (BMS) may have failed or the battery cells are deeply discharged. You need a professional with a compatible charger to attempt a wake-up.
Heads Up
Opening the deck exposes high-voltage terminals. Do not touch any orange wires or large connectors with metal tools while powered.
