Frequently Asked Questions
What is an AGU fuse?
AGU (Audio Glass Fuse) is a glass-bodied automotive fuse format commonly used in car audio amplifier wiring. The transparent glass body allows visual inspection of the internal filament — a broken or blackened filament indicates a blown fuse, eliminating the need for multimeter testing.
How do I know if an AGU fuse is blown?
Hold the fuse up to light and look at the internal wire filament through the glass body. An intact fuse shows an unbroken metallic wire. A blown fuse shows a broken or blackened/discoloured filament with a visible gap.
What is the difference between AGU and ANL fuses?
AGU fuses are glass-body fuses typically used for lower to mid-range current applications in car audio and accessories. ANL fuses are larger, bolt-down blade-style fuses designed for high-current main power runs. They use different holders and are not interchangeable — confirm which format your fuse holder requires before ordering.
Can I replace a blown fuse with a higher amperage rating?
No. Never install a fuse rated higher than specified for the circuit. An oversized fuse defeats overcurrent protection — the wiring or component may overheat before the fuse blows, creating a fire risk. If a fuse blows repeatedly, diagnose and correct the underlying fault rather than increasing the fuse rating.
How many fuses are included in this pack?
The SPF5140 contains 5 AGU fuses.
