Charger does not power on at all; no LEDs or display, even when plugged into a known-good outlet.

Safety first: Turn off the breaker and verify the circuit is de-energized before opening the charger. Do not attempt repairs if you are not comfortable working around mains voltage.

• 1. Check upstream power:
  • Verify the breaker feeding the Megear charger is in the ON position and has not tripped.
  • Test the outlet with another high-load device (e.g., hair dryer) to confirm power is present.
• 2. Inspect the plug and cord:
  • Look for cuts, kinks, or crushed sections on the input cord.
  • Wiggle the plug gently in the outlet; if power flickers, the outlet or plug may be worn.
• 3. Internal fuse check (if equipped):
  • With power off, open the Megear housing.
  • Locate any internal fuses near the input terminals or power supply module.
  • Test fuses with a multimeter and replace only with the exact same type and rating.
• 4. Power supply module:
  • If fuses are good, check the low-voltage output from the internal power supply to the control board (qualified persons only).
  • No low-voltage output indicates a failed power supply module that must be replaced.

If you cannot identify a simple cause like a tripped breaker or blown fuse, replacing the entire Megear charger is often the safest option.
