Hi guys, I got a call today on an old YT that has a Turbo Modulator on it. The machine goes through the startup and just as it starts to ramp up (at about 2 or 3 Hz) it trips out on OC. I suspect this isn't goinf to be good news, but I'm looking for any service manuals that may be availible. MN- YTM500-1047 PN- 031-00895-001
