My money is a short or open circuit for the interconnect wiring between the FS-532 and the Main body of the 951. The wiring that connect the finisher to the machine are often damaged from install and relocations.

I'd check connector CN218 at the PRCB, and CN757 & CN894P (on the FNSCB going to the DCPS) CN755, CN756P, CN893 & CN895 at the FNSCB. Make sure that you have 5vdc voltage at CN757 (hot: pins 4 & 5)(grounds: pin 2 & 3) on the FNSCB. If the wiring is intact, and you've tried multiple FNSCB's, then I'd replace the PRCB, then update firmware.

Communications errors can occur because:
*no power to the finisher
*poor connection at one of those connectors listed, or damaged harness
*blown ICP as a result of plugging in the finisher with power live
*damaged FNSCB as a result of plugging in the finisher with power live
*damaged PRCB as a result of plugging in the finisher with power live

In a very rare case, I had a dead short on a 5v sensor that was pulling down the 5vdc from the DCPS.


You didn't mention: Does the base machine run, without a finisher? I would suspect No. =^..^=

Any help pls what can i do ? :(04 FNSCB in the same Finisher?Can you tell what burned on the board? You may have a motor burning boards. Don't put it on without first finding the burnt component or the cause of it all.

That finisher board is one of the boards I managed to toast. You can get the square connector with 4 wires into the socket with 6 pins on the machine. I was hanging of the machine when I connected the finisher and managed to do just that.:rolleyes:

What firmware ver are you looking for?
