Being new to Pin ownership, I don't know the answer to this... Were the solder joints horrible looking from the factory? Or does this mean a previous owner has done horrible soldering before I bought it? (1986 machine - PinBot)
UPDATED with pics.
The one with the green circle seems to be a nice joint.
The one with the red circle seems to be a messy joint and the yellow arrows showing where it looks like an amateur burnt the wire and one of the messy joints. But all joints on this switch are pretty messy.
The pic with no circle but a red arrow, this looks like a burn mark from the switch itself. I'm having trouble with this switch registering 100% of the time. So I'm wondering if the switch is bad or if the connections just suck.
