    820-01869 Diode Mode Question

    Hi,

    I am working on an 820-01869-A iPhone SE 2020. J4200, J3900, and TUNFX all display open line (OL) in my multimeter. I got numerical value for J3200, J6400, J5700, J5800, JLAT1, and J3500. Please, what could cause this kind of problem. Thanks,

      Multimeter diode mode question
      by darkness77
      Hi, i am noob in repairing electronics and motherboards...and most of the time i am still trying to understand how things work...So, lately i have been using and testing motherboards in diode mode. Most of the motherboards that i test are not working and broken. The question is that if i use multimeter in diode mode on high 19vol rails sometimes i read fixed number in multimeter but on some other boards reading in diode mode is rising indefinitely till i read 1. I am talking on lets say ac_bat 19volt rails on motherboards. So, i dont understand how it is rising indefinitely? In theory if only...

      Macbook A1989, 820-00850, won't boot. 20V, 0A.
      by PITERPENY
      Today I have a MacBook A1989 at work 820-00850. When assembled, the laptop switches to 20 volts but the consumption is 0.00 ampere. if the motherboard is on the table then the consumption of all ports is 5 volts and0.35 amperes and does not go to 20 volts only if you assemble a MacBook.
      Here are some measurements, maybe someone can tell what the problem is.
      The initial problem was a burnt out induction coil L8504 (replaced).
      When connected to another MacBook, it constantly hangs in dfu and cannot install updates, something is wrong.
      here are some measurementsmotherboard...

      How To Test a P-channel Trench Mosfet Using A Multimeter In Diode Mode
      by dj8452000
      I am new to electronics and I'm understanding most of what I'm reading but I have a mosfet on my board that I've identified as a P-channel Trench Mosfet. I haven't a clue how to test this and what I should expect to see with the multimeter probes. I am hoping someone with years more experience than myself can help me understand how to use a multimeter to read this. Please look at the drawing I have attached to this and can you try to explain to me what I should be doing with my multimeter in diode mode and what results I should expect from a good mosfet?...

      Testing for short circuit in diode mode
      by Askic
      Hello electronics experts,

      On a few occasions I notice experienced technicians inspect for short circuit in diode mode on multimeter. This is OK and in some way equivalent to resistance mode, but more specifically I noticed that they put red probe on ground and black probe (connected to COM input on multimeter) is placed on the rail or pin.
      I wonder why is that. Why not place black probe of multimeter on the ground and red probe on the rail which is tested for short?

      Can you clarify this? When I test if something is short I use diode mode First and then double check...

      HP Power Supply 6632A: Fast Mode vs Normal Mode?

      FAST MODE vs NORMAL MODE

      I have recently acquired a HP 6632A DC power supply. I am just beginning to use it and I have been reading the manuals for it. It is the first power supply I have ever owned or used. I am a very beginner hobbyist and do not have an engineering background, as may be obvious by my question...

      I can't seem to understand what the actual use is for the 'Fast Mode' or the 'Normal Mode' on the power supply. Although the manual states what the two modes do from a engineering/technical standpoint, I don't know enough to understand what it all means,...
