Another ammeter bypass question

Hey guys,
Not looking to get torn a new one about using the search function, I have. My question is a simple one that needs a simple answer. I am doing the mad ammeter bypass because of some melted wires over the weekend. Pulled the black alt wire and the red ammeter wire which were melted and am setting up the new fused ones. Stayed with factory size 12gauge wire from alt to ignition relay and now has a fusible link.
Here is my question. I used a 16 gauge fusible link on the 12g alternator wire. Is that too small for the output(stock, 50amp I think) Should I cut it off and put on a 14 gauge or am I safe?
(I also used a 16gauge link on the red and black wires from the ammeter)

thank you for your wisdom
