In that case there is a question of how much the fuse socket can safely supply, it may be supplied by a 10 amp cable, or it may be supplied by a 100 amp bus, in the former case there is a risk of fire. If your fuse 2 gets its power not through fuse 1 then you could draw 5 amps through fuse 2 at the same time as fuse 1 is supplying 10 amps to the original circuit making 15 amps in total from the fuse socket.If your fuse 2 gets its power from fuse 1 (no power with fuse 1 removed) then there is no risk.If it's plugged in this way, Fuse 2 is getting power from the fuse slot directly and it doesn't put additional load on Fuse 1 so it'll be less likely to blow Fuse 1. Put a fuse into the Fuse 2 slot but leave fuse 1 empty, the orientation that has power going to Fuse 2 will be the correct way to plug in the add-a-fuse. To test which orientation of the add-a-fuse is correct you will need a circuit tester or multi meter. There are two ways you can plug an add-a-fuse into a fuse slot since there are two fuse legs and two fuse slots, but there is a correct orientation to plug it in. Now I just need to swap out the 15 amp outer fuses with 5 amp fuses. From what I've read, that means my fuse taps are facing the proper direction and getting power from the fuse box direct. In both tests, Fuse 2 was hot (with fuse 1 removed). So no harm in double checking the work we did. I tested my fuse taps just now to verify work of my mechanic friend - I trust him but we did use a fuse that didn't like my car. That I should remove Fuse 1 and test to see if Fuse 2 is getting Juice in the downward direction? But are they stating that it might go upward as well. I have the fuse tab with the label fuses facing downward. Presuming they are referring to A and B, are they stating that with a multimeter or LED light tester, that Fuse 2 should be getting Juice if the orientation is proper?

It states to plug in Fuse 2 and Leave Fuse 1 Empty. When they refer to orientation are they meaning the A and B plugging into the fuse box? And NOT the direction the fuse is plugged into Fuse 1 and 2, Correct?ī. I really WANT to understand this so please explain.Ī.

Leaving the Original 20 AMP (Vehicle) and 15 AMP (Vehicle) Alone?įuse tap orientation. I should replace both outer fuses with 5 AMP then (ACC + Battery). So Dashoto's kit only including 15 amp fuses is improper and dangerous.Correct?ġ.
