Re: iMac G5 PSU - no power
Diodes can read like that if they're across a coil. But that seems abnormally low -both- ways.
You'll have to remove the diode to get a proper reading. Because this is a double-sided board, you can't just unsolder the legs on the underside and get a reading. The vias or thru-holes will still make contact.
Pull it out and check it.
105v means that they're good and current is being drawn.
AC & DC voltages seem correct. The voltage at the cap seems low and that diode being shorted could be the reason.
