The S17 pro doesn't use the 6pin wires terminal, it uses busbar set up and they are pretty robust, such a scenario is almost impossible as the hashboards are fed directly from the PSU and only the fans and control board are connected to the PSU through wires, and those two draw a tiny amount of power and highly unlikely to cause such damage.
However, this can easily happen on all older models so it's always worth checking.

Just additional for the above post it could be also a control board failure. Try to check the controller if some parts near the power terminal are burn because it can also lead to a short circuit that can result in low voltage.
If you can disassemble the unit under the control board check the terminal under the control board if you can see something like this image below.
This is just a sample image for hashboard not for control board.
If you see a burnt terminal you will need to replace them.

The first PSU failed, the brand new one is not passing enough DC power, this whole thing points to low/high AC voltage.
... (and like I said I know my electricity setup works fine because this test would pass on the old PSU).
This isn't necessarily valid, when the PSU doesn't get enough power, it doesn't come out with the same results, your old PSU was a faulty one and thus it's not a good reference, could you measure the AC voltage coming out from the outlet? if it is not dead stable between 200v and 240v then this new PSU will toast soon, so be careful.
Hey guys, I have a S17+ miner thats been giving me grief for a few months now. The power supply started acting up a while back so I ordered a replacement but am seeing a new error where it only shows a value around .5 for voltage (needs to be closer to 21). This a brand new APW9 from bitmain directly, and the APW9 was the recommended PSU for the S17+. The old PSU I had would pass the voltage checks but then had problems detecting all the chains. Here's an example of the output:
Has anyone seen this before? Since it's a brand new PSU I'm not sure what I could do to fix this (and like I said I know my electricity setup works fine because this test would pass on the old PSU). Any suggestions on how to debug this issue?
