Some time ago I posted a thread where I talked about my Mac IICX having a short circuit, which was a false positive, investigating further, it may be that multimeters give short measurements under low resistances like Apple's 16 Ohms logic boards. And during all that time I tested different...

I checked the PSU but it doesn't seem to be in bad shape, I also checked the output voltages (5V) on the continuous output going to C16, however C16 doesn't reach 5V, I don't know very well what behavior C16 should have, because I saw that it charges very slowly, and gives me readings of 2 to...

Following this diagram I was able to check that the capacitors are working correctly, although I found that C16 receives 4.1V instead of 5V, it may be a minor problem but we have to check it, the reading on C9 also seems to be 4.1V.

Is correct, there is a "short" between the +12v pin and ground, sadly I was sold this Mac IICX as “turns on and POST” back to the topic, it makes sense to get these readings with what you just told me, between these two points I found a resistance of 15.4 in my case, and my multimeter beeps...

A few months ago I got two Mac IICX, of which one was unrecoverable due to a damaged battery, so I decided to restore the other one which was in good condition and supposedly “turned on” but did not turn on, and as it had some leaking caps I decided to change all the ones on the motherboard...

I am also looking for information on some capacitors, especially the C713, C723, or C733, data I have not been able to find :(, I do not know if they are really capacitors either, in this picture you can see this green component, it is the one that is damaged and I want to replace it.
