MAD ammeter bypass question

Just one little problem with “shunt wire” by-pass that those who promote it don’t seem to understand, it by-passes/alters all designed circuit protection for this electrical system.

Thank You. Very informing video!

As far as removing the original charge wire from the alt stud while utilizing a shunt to the relay stud.........

This would appear to remove the parallel fusible link issue as it pertains to an under dash short while still keeping the charge load under the hood. In the event of an under dash short, the original fusible link from the batt. would work as designed would it not?

Other than the ammeter not registering, is there any other downside to this set up assuming that the removed original charge wire is well insulated?
