Reverse Polarity Fuses Circuit Question
Ok fellow scientists :) What is so special about the reverse polarity fuse circuit in a converter compared with just having a fuse on the positive output wire? I yanked the 7355 from the trailer ...

You're correct. If reversed polarity, +12V battery goes to the ground of the secondary winding center tap, through the 4 diodes and the fuses, and back to battery ground. That should blow the fuses.

If you look at the schematic that KJINTF posted, other than the small filter capacitors and inductors, the last thing in the circuit is the diodes.
