F28-3 on KM 7145

[copytechman]

From da book:

F28-3 Separation lightning abnormality

When the EM signal (separate_em) is detected 3 times at the specified intervals, this phenomenon occurs 5 times in 1 job. The main body stops immediately, and the RL1 (Main) turn OFF.

Separation corona
HV (High voltage power)
CB (Main body control board)

Yup, go with what the prior poster said, either the block and insulators on the door or the trans sep unit itself. Been there, done that!

Regards!

try replaceing the T/S corona, also look at the T/S transfer block on the door this unit is known to eat these parts up.
