It’s a good idea to always have a fuse in every power supply line. Then if there is a reverse protection scheme built into a rig the fuse will blow first. One time I blew an early Chinese radio (without protection) because the battery I bought at a swap had a RED price tag right next to the negative pole..... lots of smoke. Now on all batteries I use I mask off a large area by the positive pole and paint it with red paint...... AND have fuses in ALL of my power cords.
On another rig it did have a reverse protection diode and it blew because I didn’t have a fuse in the line. I was lucky because I caught it right away as the diode was cooking and all I had to do was replace the diode.
Now I have confessed my sins. I feel better!
