Schematic Diagrams/Block Diagrams of Fanuc Modules

[leor]

Hi there...I'm having trouble repairing this servo amplifiers and power supplies by fanuc.Most of the time I only make it by "guessing" or direct substitution method.These methods are very expensive to do because we don't know if they were realy good or bad components.That is why I thought if we only have a manual, or a schematic diagram to let us trace the flow of the circuit may lessen the job and obviously make it more easy troubleshooting.
The question is, Has anybody who has a copy of it may upload or link it for anybody who needs it?
Like me of course, I need one for a servo amplifier A06B-6079-H208 and for a Fanuc BETA I series amplifier A06B-6134-H302#A. Thanks in advance and more power to us.

I only got lucky once and had a board with a visibly damaged resistor. Pulled and verified it was bad. After replacing it all was well. So I know your pain. I would love to have some documentation on the A06B-6079-H208 (as well as lots of others)

Sadly...
