I`m troubleshooting on the -88 mod Maho mh700s with grundig steering.
Problem is that the power supply to the drives doesn`t get any power, the contactor that delivers wont get in.

If I force the conactor the fuse for the DC intermediate course goes out!

Also during start up of the system, all drives passes the test, but one that says "FAILED"

The faults I`m getting are:
I01: Interface not on power
M01: Checksum error constant memory (RAM-memory)

Please help and quick

M01: Checksum error, means that any machine constant has been changed from the last time the machine running. If you have change any MC, be sure that you have switched back the MC switch when the machine is on power! If you change MC and then switch off the main power when you still are in the MC meny, and then the MC switch you will got the error code M01. I´ll hope you got what i mean?
