If there was 0.7V over the polyfuse would the Pi boot? I'm no electronics expert but it seems signs are pointing towards a 'bad' cable. Since I haven't tried to replace it yet but have replaced everything else several times over it might be the simplest for me to order a new one. I don't see how I'l...

Thank you for taking the time to answer. I have gone through the trouble shooting and I eventually bought peripherals from the compatibility list.
