Fujitsu-General Fault

Ok been back. I got mucho info.

Serial Signal Test (First diagram posted by Nike)
Between terminal 1-3 170-200V. I think this is too high as the diagram says 70-130V.

AFM Test: (As the second diagram posted by Nike)
+ - 360KΩ (correct)
- N1 0.3Ω
P + 330KΩ
L1 L2 361KΩ
P N1 0.3Ω
L1L2 Control ∞
L2 N2 ??? (I could not find the N2 terminal)
L2 P 0.3Ω
p L2 0.3Ω

All these bar the first and test to the control box are nowhere near what they should be
As a side note, I tested the leads on the multi-meter and they read 0.3Ω.

Finally the fan motor. The motor is not the same as the one posted by Nike. I posted the winding readings earlier in this thread.
This is what I have.


So after all this I think the AFM is screewed. Do we all agree?
