Blade Fuse | 15A (amp) ATC

15A ATC Blade Fuses | Vintage Honda

Once you've swapped your vintage Honda's crumbling glass fuse holder for a Posi-Lock blade holder, you need blade fuses to go in it. These are the 15A ATC fuses for the job, the same blade fuses found on nearly every car on the road, so you can grab a spare at any gas station. Sold in packs of 5.

Why You Need This

Every vintage Honda we support runs a single 15A fuse as its main circuit protection. The factory used a glass tube fuse, but those get harder to find every year, and the original holders corrode and crack. The fix is a Posi-Lock blade fuse holder and a modern ATC blade fuse you can replace anywhere. Keep a pack in your tool roll so a blown main fuse never ends a ride.

Specifications

Model-Specific Notes

• Single-fuse bikes (CB175 / CL175, CB200, CB350 / CL350, CB450 / CL450, CB500T, CT90): One 15A fuse protects the whole harness, so this is the only fuse you need.
• Multi-fuse bikes (CB360 / CL360 / CJ360, CB400F, CB550, CB750): The 15A is the main fuse. These bikes also run smaller sub-fuses, so you'll want our 7.5A ATC Blade Fuses for the head and tail circuits.
• CB125S: Came from the factory with a single 10A fuse, but a 15A works fine, and the other CB125 variants use a 15A.

Installation

Difficulty: Beginner

Tools needed: None

1. Make sure your blade fuse holder is clean and free of corrosion.
2. Put a light dab of dielectric grease on the metal blade connectors.
3. Push the fuse into the holder.

Frequently Asked Questions

My original glass fuse is a different length than the replacements I can find. Will switching to blade fuses fix that?

Yes. Old glass fuses came in several lengths, so the exact replacement can be hard to source. Moving to a Posi-Lock blade holder and these ATC blade fuses gets you on a modern fuse you can buy anywhere, in a fixed standard size.

What holder do these go in?

Our Posi-Lock Blade Fuse Holder, which splices into your harness and replaces the old glass-fuse holder. These fuses are made for it.

Standard or mini blade fuse?

These are standard full-size ATC/ATO blade fuses. The Posi-Lock holder also accepts the mini size if that's what you have on hand.

Does my CB125 take a 15A fuse?

Yes. The CB125S left the factory with a 10A fuse, but a 15A works fine, and the other CB125 variants use a 15A from the start.
