Yeah, this voltage could be 2 to 7 v, However if you remove the psu, or at least disconnected from the motherboard and you add a 3.3v voltage to pin 4. Just as this picture shows, http://www.ourdreambox.com/ubbthreads.ph...-psu-switch.jpgThan this pin 2 should give 6vdc or a bit higher, at least when I tested this way, with several psu's they were al 6v+.

Just decided to measure a couple old PSU's I have to see if they are any good to use. Are either of them repairable or are their measurements too far out. Anything strike you as simple? I don't think I've every replaced caps in them. Both are 25X10 code.
Original PSU was faulty when it arrived.
1 - 0.63K
2 -
3 - 29.56K
4 - 13.38K
5 - 13.96K
6 - 13.7K
7 -
8 - 8.52K
9 -
10 - 20.53K
11 -
12 - 4.7K
13 - 4.7K
14 -
1st replacement PSU
1 - 8.75K
2 -
3 - 32.98K
4 - 14.92K
5 - 15.03K
6 - 15.03K

Further to this, I just got a chance to test the PSU currently in the DM.
It is the later style 5L0565.
1 - 11.9K
2 -
3 - 53.1K
4 - No Value
5 - 22.09K
6 - 21.63K
7 -
8 - 9.11K
9 -
10 - 30.36K
11 -
12 - 8.22K
13 - 8.22K
This current PSU seems ok based on that alone.

Psu 1, 14v issue.
Psu2 (2.5v) doubtful.
Psu 3 seems to me fine.
