    Welcome to AAC!

    How old is it? Who made it? What makes you think you need a new circuit board?

    Did you reattach the wire before checking to see if it worked?

    Why did you expect it to work without reconnecting the wire?

    Do you recall looking at the wire before it became disconnected? If you knew how much slack it did or didn't have, you could use that information to narrow the search for possible attachment points.

    If you don't have any idea of what it looked like before it broke, look at all of the points where it might have connected to see if there's any indication of a prior wire attachment.

    If the wire is solid, you may see a hole (or similar) in a joint. If it's stranded, some of the strands may have been left behind.

    Not likely and don't even think about it. Color coding is often used in assemblies to avoid making connection mistakes. Can't think of any valid reason for a manufacturer to connect a black and red wire. The logical thing to do would be to simply use the same color wire.

    If you continue to test things without addressing the known issues, you could end up making things worse.

    Don't connect things unless you're absolutely certain it's correct. Rushing to "fix" things when you're not certain of what you're doing could have disastrous consequences.
