On the 2007 Honda Accord 3.0 V6, the main fuse for the alternator is located in the under-hood fuse/relay box, near the battery. Pop the hood and you’ll see a black plastic box with a removable cover — flip it open and check the diagram under the lid.
You’re looking for the “ALT,” “Main,” or “Battery” fuse — typically a large 80A or 120A “mega” or “bolt-down” style fuse. It’s not a small plug-in blade fuse, so you’ll need a 10 mm wrench to remove it if it’s blown.
If the alternator isn’t charging, also check:
- The smaller IG (ignition) fuse in the same box.
- The battery terminals and ground connections.
- The alternator plug for corrosion or a loose connection.
That big main fuse is your first stop, though — it’s the one that protects the alternator output circuit straight to the battery.
In any case, I would recommend grabbing this 2005-2007 Honda Accord Service & Repair Manual, as it covers the fuses of this particular vehicle in detail, along with every procedure you need.
