what is the large coil like thing ?

You might also want to do some research on how buck regulators work. The coil-like thing is a coil.

Well for a start, what is the voltage into and out of the big power inductor?

The regulator's voltage is set by a digital potentiometer ... The default value is right in the middle, which is why some "dead" S7 will start to 9.3V ... the value gets updated by a little microcontroller (PIC12F1572), which pushes out a fresh value from memory as soon as it kicks on.

Why are you using a USB scope to look for 1572? It's something you look for with your eyes. It's written on top of the chip. Without a board in front of me I have no idea what the silkscreen label is, but I do know it's the 8-pin SOIC device with PIC12F1572 written on it. Which is all information you had.

But anyways, first thing you need to do is measure the voltage at the place you've been told to measure the voltage (I'm pretty sure there are even clearly labeled pictures in the potentiometer fix thread). If it's not in the range you've been told to look for to see if the PIC is dead, you don't need to worry about all the other information you were given because it's not the fix you need - which is also information you were given.

Sorry if my criticality comes across as dickish. I'm well aware I tend to expect more out of people than they're used to and am frequently disappointed, but I don't intend to change. It either makes people leave me alone or work to be better, which in the long run are both winning outcomes.

I understand your frustration, if you was to ask me about certain isolations, EICR tests, permits, earth loop impedance, remote I/O, Ifix, Calculating motor size/torque/Rpm /Wattage etc i would be the same.....lol

I wish your first answer to ' what is the coil thing' i presumed it was some form of inductor BUT on Youtube some nutter ( i will find it and and post it, i will make you even angrier as i think he is checking the main caps with ONLY a Mulimeter..lol
) If you has said it was the inductor i would have been testing this ages ago...

Anyway thanks again for 'putting up with'

'I will be back'....lol
