not quite sure what your saying here but this is just me trying to use the chip i already have just stuck on trying to make it now show a low battery on one. it flips mattering if i have the thin red wire connected to a positive but no change while connected to negative. so i dont know if i need to solder the small wire to somthing to trick it. its the wire that goes to the plunger on the battery door.

Not sure it’s a good idea to throw power at it, randomly guessing. Not that I haven’t foolishly done so myself but maybe you learn from my mistakes.
Did you check the connection with an Ohm meter before you disconnected the mod board? If you checked the connection from the positive battery terminal to the board or switch, and checked the connection from the negative battery terminal to ground, and checked the board negative to wherever it went and you had good connection for each, than swapping out batteries for an external power supply will only give you the exact same result. I think that is what you are seeing from how you described it. It sounds like the problem is not with the power input but maybe the board itself?
Always take pictures and draw a connection diagram before disconnecting wires.

If its a topside dual its the battery door. Mine does it as the doir is warped i have reshaped it numerous times. Finally gave up ill get a new battery door after christmas. He has probably shorted the board out playing with it
