Further along reading voltages and 1 current that seemed odd since the unit was off.
And it lead me to some questions as to how to take the readings.
I desoldered L3 and put the ammeter in series at the connection. It read -22MA even with the unit turned off. Is that usual ? And I dont know where to put the + and - probes, hence the -22MA. It could be +22MA.
And when I take the voltage readings on the top of the PCB, I dont know at which end of the component to place the +probe or the -probe with the other at ground. So sometimes I have been doing it both ways and indicating both of the readings and separating them with a comma. Like on the schematic that shows the transformer, C61 is 19 , .08 etc.
Where the 32V should be, it is reading 38V. I dont know if that is within tolerances or not. I cannot read datasheets to see wassup. The resistor R10, just before Q2 transistor 2SC1815, reads 38,8 with a drop of 29.4. I guess the sum=38 so all is well.
Q2 transistor 2SC1815 reads a 0000V on the base. Does that seem right ?
I took the readings at each pin of the IC, LM7000 and wrote them onto the hand drawn LM7000. The LM7000 is way obsolete so if it is faulty it will be difficult to get a replacement.
So, are these readings what are to be expected and where should I start looking for faults. I have been trying to trace the schematic, left to right, top to bottom, as that is what another site recommended. However that scheme seems to fall apart quite often.
Oh yeah, when I was looking at the FE407, titled U1 Front end, its a sealed box so its tough to get many readings although I took a reading at pin 6 and it was 2.85V. Pin 6 says OSC so is that supposed to be a sine wave and should I be able to read it using AC volts ?
Since the blowing fuses situation seems to be stable and I am getting the correct voltages out of the power supply,
except 32=38, do you think that I should start another thread since this one seems to be getting quite lengthy and cluttered with my early fumblings ?
Thanks again
