The mis-wired left sling doesn't affect the trough. It messes with some other switches. A pop or target or orb lane.
(1) Right sling, bottom switch, non diode switch. Left sling is a little different.
(2) Unsoldering the wire from the tab, the wire will stay intact, heat shrink or tape it. Then run the gray jumper you see in my pic.
(3) Your left sling is wired wrong. The fix is different than the right. You have 3 white wires.
1st wire comes from elsewhere and is attached to the non band diode connection. Leave that one alone.
2nd wire comes from elsewhere and goes to the no-diode switch. Unsolder or cut that wire and attach it to the non band diode connection where the 1st wire is attached.
3rd wire jumps from no-diode switch to non band diode connection. Move the wire from the non band end to the banded end.
I'm glad I could help.
