Schematics for BG aren't available online, but I'm pretty sure you have your black/ yellow and blue/ yellow wires reversed. Black and yellow wire goes to the non-banded side of the diode and vice versa. Your EOS switch connections will be correct once you reverse those wires. Don't change those. Pic below is from a Swords of Fury. Be sure to test diodes for shorts before you power it back up.
