r90h not detected

[jeff8451]

I have a R90h drive which needs fixed, and some advice for some. i had a drive blow, which I beleave was due to connecting 2 legs of 110 together after the transformer. i considered the power to be dc. This fryed a transformer and blew a transistor on the drive. I now run each drive on its own transformer.

Now for the drive: I think this drive that won't be detcted is the one that blew. when I put it on the motherboard all drives are not found by the tuning program. I saw in the yahoo groups that some repair these drives. What do i need to do to fix this drive? any ideas? help plz this makino mill project just keeps on going. lol thanks in advance jeff
