Ford home charger shows E005 and refuses to start; sometimes occurs after a power outage or surge.

Safety first: Only a qualified electrician should open the service panel or measure live voltages. Turn OFF the charger breaker before any inspection.

• 1. Verify breaker rating: Confirm that the charger is on the correctly sized 2-pole breaker (commonly 40A–60A depending on model) and that both poles are tied together.
• 2. Check for obvious wiring errors: At the charger’s internal terminal block (with power OFF), verify that two hot conductors and a ground are present, and that no neutral is incorrectly connected where not required.
• 3. Measure supply voltage (electrician only): With a multimeter, measure line-to-line voltage at the charger input. It should be approximately 240 V. If significantly low or high, the issue may be with the home wiring or utility supply.
• 4. Inspect for loose connections: Tighten any loose lugs at the charger input and at the breaker (with power OFF). Loose connections can cause voltage drop and arcing.
• 5. Reset after correction: Once wiring and voltage are confirmed correct, turn the breaker OFF for 2 minutes, then ON, and attempt to charge again.
• 6. If E005 persists with correct wiring: The internal voltage sensing circuit on the control board may be faulty and require replacement by an EVSE technician.
