How do I fix a Freestyle 5 oxygen machine?
I have tried to use a variable power supply to power it on, but it doesn't work. I am guessing that it needs some sort of voltage signal from the battery balance leads, but I am not sure what.
I tried connecting the switch pin to gnd and 5v, but neither worked. I used 16V to power it, which is the correct voltage. I have rebuilt the battery pack, but it wasn’t working after I did, even though the batteries and connections are good.
Here is a google photos link to the oxygen machine:
