Ok for those interested. Indeed I ordered myself a dc power supply. Now the thing works flawless. So from the s17 series beyond, you'll need a dc power supply. Original psu won't do it.

Not sure where you bough the tool from, but on Zesbtc they have a huge warning that says:

Notice:

If you test a combined mining machine (a mining machine with its own power supply), you must use the power supply that comes with the mining machine to power the test fixture and the Hash board. It is forbidden to use any third-party or adjustable power supply! Otherwise, it may cause equipment failure!

You said you have S17+ which is a "combined mining machine", so you might be careful when using an external PSU, as for instruction, zeusbtc has a truckload of pdf files, search around and you will find the manual for the fixture tool. Good luck

That's just standard warning Zeus is putting up so no one would sue him for anything going wrong afterwards. The Asic.repair kit suggests everything from the S17 series and beyond to use an adjustable DC power supply. I just tested a bunch of my hashboards. Did the job perfectly. Very easy and saves LOADS of time. The thing cost me a lot but was worth every penny. You do need at least some basic knowledge about electronics tho. But then again, doesn't matter which test fixture you buy, as soon as you wanna start repairing these hashboards, you need some basics before starting. So yeah, I'm gonna keep you guys updated on how this goes...
