Frequently Asked Questions

What type of fuse does my car use?

Most modern cars use blade fuses in standard (ATC), mini (ATM), or micro (APM) sizes. Check your owner’s manual or look at the fuse box cover for the type and amperage. Older vehicles may use glass tube fuses. Our research shows that mini blade fuses are now the most common in newer models.

Can I use a higher amp fuse to fix a blown fuse?

No. Using a higher amp fuse can cause wiring to overheat and start a fire. Always replace with the same amperage rating specified by the manufacturer. Our evaluation of safety standards confirms that over-fusing is a leading cause of electrical fires.

How do I know if a blade fuse is blown?

Look at the metal element inside the transparent housing. If it is broken or melted, the fuse is blown. Some fuses have a small window that shows a clear break. Color-coded housings also help identify the amperage, but you must check the element.

Are expensive fuses worth the extra cost?

For critical circuits like airbags or engine control, we recommend name-brand fuses from Bussmann or Littelfuse. For non-critical items like interior lights, generic fuses are acceptable. Based on owner feedback, expensive fuses offer better durability and fewer failures.

Can I use a resettable circuit breaker instead of a fuse?

Yes, but only if the circuit breaker is rated for automotive use and matches the amperage. Resettable breakers are convenient for accessories like winches or audio systems. However, they are bulkier and may not fit in standard fuse boxes. Consult your vehicle’s specifications first.
