Dear Sir or Madam, we have about 2000 SMPS from SAFT POWER SYSTEMS (about 700 "SM 1600" and about 400 "SM 1800" models). We have now a repair success rate of about 60%, but we still need the detailed electrical wiring diagram or a service manual for these models. Can you help us please for prividing the original diagram and/or service manual. Thank you.
