I can replace the ICP and it may last 1 sec, 1 minute, 1 hour, or a month before it blows again. This unit came from a Konica Minolta dealer with the ICP1 blown, I replaced it and it ran for nearly 2 years before blowing again.
I've have looked at the wiring harness's till I'm cross eyed, we can't find anything shorted, cut, or damaged in any way. We have replaced the following electrical components. (Post Insert-er from an FD-501 makes up most of the parts)
PDB (Punch Drive Board)
FDB (Fold Drive Board)
FDOB (Folder Operation Board)
PIDB (Post Insertion Drive Board)
DCPS (DC Power Supply)
JAMIB (Jam Indicator Board)
MFDB1 & MFDB2 (Multi Feed Detection Board's 1 & 2)
Sensors replaced (21 Total) (PS1, PS5, PS6, PS35, PS36, PS44, PS47, PS31, PS38, PS39, PS41, PS42, PS45, PS48, PS46, PS37, PS40, PS32, PS33, PS43, & PS34)
Motors replaced (6 total) (M1, M17, M3, M9, M8, & M7)
Solenoids (SD13 & SD14)
Variable Resistors VR31 & VR32
Clutches CL1 & CL2
The FDCB (Folder Control Board) is the last original board in the folder.
Any suggestions or anyone have an FD-503 they could sell?
