The six wires on the left connect to the three speakers. Two of which are mid-range drivers and the third is for a tweeter. I'm afraid I don't have a signal generator unless that's a fancy name I've not heard of before.

I'm happy to hear what you think on how I can test them without breaking them.

Are the mid range drivers the same? If so you could look for symmetry in the circuit. The odd man out is the tweeter. In this case it looks like the pair of wires going to the 1 ohm resistor would be for the tweeter.

Then is getting the phase (+/- correct) - you can do this by listening. I would get the mid range figured out first.
Also, you have large and small spade connectors - are the drivers (speakers) labelled? I assume they have matching male ends, so then the phase is already worked out as well.
Should actually be pretty straightforward. Start with very low volumes.
I have access to a signal generator if you want to send over the unit. May take few days to have some time. But simple enough.

Also, a picture of the bottom of the board would be helpful. Your pictures are huge - try resizing before posting.
