jeez I am so bad I didn't update this.
that fix worked for a bit but not for very long.
I took it apart again and took the little black slider off that moves along the middle rail. Inside it are 5 or 6 contacts that bridge those circuits depending on its position. I removed the contact for the reverse circuit (the bottom one IIRC), flipped it 180' and reinstalled... now it is really fixed. (fingers crossed... so far so good...)
good luck with the manual fix!
