Got one of these with a bad switch, so I'm trying to true bypass it with a 3pdt (using the standard method). I have q104, q105 removed, a jumper from q105's outside pins, and q108 removed completely (all according to the layout below, so hopefully the transistors in question are correctly labeled on the layout). Circuit works fine, but the red and white wire (originally going to the switch - mom.sw on layout) still unlatches the circuit. This would be fine, but when power is removed, the circuit unlatches, and when power is re-attached, the circuit remains unlatched until you touch the red/white to ground.

I don't understand how the wire still engages/disengages the circuit with the parts in question removed. Any advice on this? I really appreciate it. It's driving me crazy I can't figure it out
