As fate would have it the arrows on HiFi fuses don’t indicate direction the fuse should go. In fact HiFi Tuning advises customers to try each fuse both ways to determine direction. It is an old wives’ tale that the arrow points in the direction of the signal flow or electricity flow. It’s also an old wives’ tale that the fuse should go in the opposite direction from the direction of writing on the fuse. The little diode logo or arrow is simply a way to help you remember which way the fuse went just before you flip it. This feature is especially useful if you accidentally drop the fuse with clumsy fingers whilst flipping it or forget which way you had it. This means HiFi Tuning doesn’t "pre-set" each fuse for direction. But HiFi Tuning IS AWARE fuses are directional, we know that for sure. All fuses. Even fuses in AC circuits. So the probability is 50% that a given fuse was inserted in the correct direction. Therefore the only way to procee when one has multiple fuses is to flip each fuse one at a time rather than all at once.
