Have I Figured Out This Fused Power Supply Correctly ?

[frank rabbets]

Pictured is the power supply wire for the dash cam I've just bought. Instructions are to remove the 10 amp fuse from the cars fuse box and then replace it with the spaded wire then plug in the removed fuse. Is the following correct? The 10 amp feeds directly in to its original contacts thus protecting the original circuit. The 2 amp fuse would blow if it were using the same configuration so one spade must go to one side of the 10 amp fuse (both side of the fuse are + live with a good fuse) and the other supplies the camera. Now if the main fuse blows it will render the camera dead, or is that dependent upon which way round I plug the assy in to the cars fuse location. (I think it can go 180 deg round).

Negative feed just goes to frame.

Thanks

Correct.

One way round the 2A tap off fuse will be added after the 10A and the other way round before. Sonplug in without the 10A in and see if it works, if not rotate 180 degrees then the 2A is tapped from the input to the fuse, the live side as it were.

Thanks I just like to know exactly how things work. Orientation is not important to me as its unlikely the 10 amp will blow and he 2 amp will work in either position as long as 10 is intact. Good way of checking exactly what part of the circuit the 2 amp comes off. I might just make it come off to be self sufficient. Now I have to decide exactly which fuse to remove so camera comes on with ign. It's a 2013 Mk7 Golf. Millions of fuses.

Out with the multimeter then.
