Charger indicates error when vehicle is connected; vehicle may show ‘Grounding issue’ or ‘Check earth connection’

Safety: Ground faults can be hazardous. If you are not comfortable working in the panel, contact a licensed electrician.

• Verify ground conductor: At the Grizzl‑E, confirm that the green or bare copper ground wire is securely attached to the ground terminal and that the terminal is tight.
• Check continuity: With power OFF, use a multimeter to check continuity between the Grizzl‑E ground terminal and the service panel ground bar. Resistance should be very low (near 0 Ω).
• Inspect for corrosion: Look for rust or corrosion on ground lugs and bars. Clean or replace as needed.
• Panel inspection: Ensure the ground and neutral are properly bonded only at the main service disconnect, per local code.
• If wiring is correct: A persistent E06 with verified good grounding may indicate a failed ground monitoring circuit on the main control board, which will need replacement.
