Hello, everyone! I just received my ARC not long ago and am still getting used to it.
When you use ARC to test S19, does ARC provide a PT2 level test? (Or this test result is equal to a passed PT2 test) Thanks for the answer!

Similarly, in my test, I use 14V as the upper limit of DC voltage, I will continue to run the test program until the hash board reaches 55-60 degrees Celsius (the hash board can reach 75 to 80 degrees Celsius in normal use), when the temperature exceeds At 55 degrees, I get a lot of errors, but until 55 degrees everything works fine. What do you think? Thanks!

it means that you have a fan problem. " fan lost(3)" means that three fans are working fine and one is not. It does not identify which fan is lost. Replace the bad fan, if it does not work then replace the Control Board.

Shorting Rx. Meaning bring 1.8 volt from the same voltage domain to RO from chip 31 32 33 etc Find a cap where you can jump the 1,8 volt to the RO test point. Start the tester with the wire connected and if it counts to chip 31 and so on

From 31 - 32 etc When does the counting stop on the tester

Forget the resistors and caps. Make sure they are in place. Compare them with a working board. Make sure that the little resistors are not broken. Touch them with flux and a needle to see if they are ok. With a heatgun with 360 degrees

If the 2 sides of the resistior are shorted (0 ohm) it means that there could be a shorted cap or a chip or something else that is causing the short, if you inject voltage you could see where the current goes getting hot to identify the origin of the short.
