Where is the ground wire on a headlight?
The ground wire is normally a short wire attached to the vehicle chassis near the headlight. The vehicle chassis itself provides the remainder of the return path to the vehicle battery. Remove the connector from the back of the headlight.
Why are the low beams out on my Honda Accord?
2005 Honda Accord. Replaced the fuses even though fuse looked good. Took it in to have bulbs replaced but still did nothing. Went on vacation for about 2 weeks, car was in the garage. Came back used it first night everything fine. Next day went to turn on headlights and both were out, but high beams worked.

How does ground connection work on Honda low beams?
Connection from the vehicle grounded frame is accomplished via a wire conductor or incorporated into the circuit board’s thin film grounding conductor pattern routed through one of the hold down bolt/screw into the metal frame to achieve necessary ground connection.
Where are the ground connectors on a headlight?
The reference below shows typical headlight wiring schematics. Some dual-element headlight lamps have separate grounds for each element. These are the four-wire connectors. Two wire connectors are usually only found on the high beam for dual headlamp vehicles.
How do you know if a headlight wire is ground?
One should read 12 volts. This is the high beam power and this wire is not ground. If there are only two wires, the remaining wire is ground and you should turn off the ignition and headlights and go to the next section. If there are three or four wires, go to the next step.
What causes a car headlight to not turn on?
Problems with the ground circuits to headlights can cause them to dim or not operate at all. The ground circuit provides a path for the electricity from the headlight to return to the negative terminal of the vehicle battery. The ground wire is normally a short wire attached to the vehicle chassis near the headlight.
Where is the grounded test light located on a car?
On older cars, the switch controls headlight and tail light power, instead of grounding BCM triggers. For these systems use a grounded test light and test for twelve volts at the rear of the headlight switch connector (removed) on one or two of the terminals or wires.
How do you check for a bad ground on a headlight?
Turn off the ignition and headlights. Set the multimeter to measure resistance (ohms). Place one lead on the chassis or the negative terminal of the battery, and the other lead to the ground wire. If the resistance shows continuity (zero resistance) then the wire is okay. Otherwise, go to the next step. Check the resistance of the wire.

When to replace a wire on a headlight?
If the resistance shows no continuity (infinite resistance), the wire is broken or not connected properly or severely corroded. The wire should be replaced or the faulty connection repaired.
