the fuse block is right after the master switch.
1,2,3 go to the fuse number 1, 2, 3... then the output is 8, 9, 10 to the AB relay.. then the output is to the drive transformer. This is making the drive transformer not getting the correct input voltage so the out put voltage is correct. ( i think )... well, at least the output to the SimoDrive, and the SimoDrive is showing the error.
Either that transformer is bad or that relay is bad it seems like to me. I have heard that AB relay in the past do some strange noise things.
I cannot find a part number on that transformer to even begin to try and track one down.
