all fans don't work
-
with tester I checked continuity and everything seems ok. I attach the photo I believe tr5 broken. I don't know how it is possible. however no fan works
-
I can't say more than that. I know that everything has gone well to date, it didn't take this problem, it forces me to replace the whole board I think. without fans no one can go.
-
Try measuring as indicated, should beep or measure close to 0 ohm in all cases.
-
there is continuity between the jumper and fan bridge and fuse. the size of the tr5 I did not understand how to do it
-
I had seen badly I checked everything also the continuity between resistance and fan and power supply all ok
-
@massimilianoconti said in all fans don't work:
all ok
if you the connect a fan to the always on ports and it doesn't work, then the fan (or power supply is broken)
To check mosfet TR5 you can mesure from Vfan- and GND like shown (use diode test --|>|--)
-
the voltage is not zero, it marks a value
-
I'm sure it won't kill you to be specific, about both measurements, need to reverse polarity and repeat measurement.
-
I see + 0.3 v and -0.3 v
-
Negative reading on a diode test, and fans that dont work when they should. I think you need an excorcist, or maybe some pictures showing measurement and meter.
