Thanks for keeping up the help. I’m really not sure how I could post voltage measurements for the pins though tbh, I’ve only got the light to run with it assembled so far as I need the negative path to be intact. If I use a DMM to make the connection and get it running I won’t have any hands free to measure voltage on the pins. I’m not sure how I could access them with the cell connected either, as they are so small and would be tucked under the positive end.
I don’t mind going with a ‘best guess’ connection on the inductor side and getting it by trial and error, as long as there’s not too high a chance of permanently destroying the circuit…
Oh, and yeah the component on the inductor side has no markings. I didn’t have any luck with the markings on the other components either, apart from the 2300 one which I think I found on aliexpress but looked unrelated to PWM.
