So in a rare moment of rational thought i said. Should there be, with all of the diodes pointed in the same direction forward voltage in one direction between the output of the doubler and the input? Or at least from this photo from the ground to output as displayed
I got nothing on either, in either direction, surely i should be getting some kind of reading in one direction
I set up the mighty [and newly repaired] IT1121 for diode testing you can see a control here at .1v divisions
Take a look at this section i stumbled across, i backlit these three diodes so you can see the traces, see the symbols on the board, they essentially all point in the same direction in series....
Look at CR903, it has different markings than the other two in series and its dash line is contrary to the etched symbol
The diode itself tests fine, but obviously only when the leads are reversed
So I can test from the power transistor all the way TO CR903
But not THROUGH CR903 to P907 wire connector as shown
Can it be possible that the diode is backwards?
?? Its definitely different looking than all of the others. Your thoughts?
