The negative terminal is the black (-) post on the 12V battery located in the engine bay, typically on the driver's side.
For drivers seeking to jump-start the vehicle or perform battery maintenance, locating the negative terminal quickly can prevent sparks and damage. The 2020 Honda Pilot uses a conventional 12V battery in the engine compartment, and the negative terminal is one of the two posts on top of that battery. Understanding which post is negative and where to connect a ground can also help when using jumper cables safely or when testing the battery's condition.
Where to locate the battery and identify the negative terminal
Use this quick checklist to pinpoint the negative terminal on your Pilot’s battery.
- Location: In the engine bay, typically on the driver's side near the fender and the fuse/relay box.
- Terminal identification: The negative post is marked with a minus sign (-) and is connected to a black cable; it may be partially covered by a black protective cap.
- Positive terminal: The positive post usually has a red protective cover and a plus sign (+).
- Accessibility: If the terminal is obscured by a cover, gently remove the cover to reveal the post beneath.
Conclusion: The negative terminal on the 2020 Pilot is the black (-) post on the engine bay battery. If you can’t access the post directly, you can use a clean, solid ground point on the engine block or chassis as an alternative negative connection.
Safe jump-start steps and grounding guidance
Before connecting jumper cables, review these steps to minimize risk and avoid damage to electrical components.
- Park both vehicles close enough for cables, but ensure they do not touch. Set parking brakes and turn off both engines.
- Open the hoods and locate both batteries. Identify the positive (+) and negative (-) terminals on each battery.
- Connect the donor vehicle’s positive clamp to its positive terminal, then connect the other red clamp to the Pilot’s positive terminal.
- Connect the donor vehicle’s negative clamp to a solid ground point on the Pilot, such as an engine block or chassis ground, rather than directly to the Pilot’s negative post if it’s difficult to reach.
- Start the donor vehicle, then attempt to start the Pilot. If it starts, let it run for a few minutes to recharge the battery.
- Remove clamps in reverse order: negative from the Pilot first, then negative from the donor, followed by the positive clamps.
Conclusion: Following proper grounding—preferably a solid engine block or chassis ground—reduces the likelihood of sparks and protects sensitive electronics. If the Pilot doesn’t start after several attempts, there may be a deeper electrical issue requiring service.
Additional grounding options and common questions
If the battery post is difficult to reach or covered, these alternatives can help ensure a safe, effective connection while jump-starting or testing.
Finding a reliable ground point
Look for a clean, unpainted metal surface in the engine bay to establish a solid ground. Common options include:
- A machined bolt on the engine block near the cylinder head
- A chassis ground bolt near the strut tower
- Unpainted metal on the alternator bracket or other sturdy mounting points
Conclusion: When the negative post is hard to access, a clean engine-block ground provides a safe alternative for establishing a solid electrical ground during maintenance or jump-starts.
Summary
For a 2020 Honda Pilot, the negative terminal is the black (-) post on the 12V battery located in the engine bay, generally on the driver’s side. To jump-start safely, connect red to the positive terminals first, then connect black to a solid ground on the engine block or chassis rather than touching the dead battery directly. If you cannot access the post, use an appropriate ground point and consult the owner's manual or a technician for model-specific guidance.
