miller legend aead 200le low open current voltage

[armytankwelder]

I have acquired a miller legend aead 200le and have got all my RPM'S set. Now checking my OCV and there low. Ac is reading 52 and should be reading 80 and dc is reading 33 and should be reading 72. I've clean the slip rings, checked the brushes for now and have to decide where to go from here. Aux power is good and normal. Miller tech said today sounded CR3 was wired backwards, but it appears to he factory. Anyone had this problem or have a good answer?

And what is the frequency (hz) tested at the auxiliary terminals , and in high weld auxiliary setting

High side rpms are 3000. When I got it it was doing around 2700, I've adjusted it to 3000. This unit only makes 60 hz power at 1850 rpm. It dont weld and produce 60 hz power at the same time. Also the guy had unplugged the voltage regulator on the engine and I can't figure it out. I'm wondering if that is part of the issue it being unplugged. It has 3 wires, the way I understand is 2 wires come off the stator "ac" and 1 hooks to be 12 volt dc. What I can see is 1 of the wires is grounded....I'm lost. I've took a meter and can't make heads or tails out of it. Sorry I got off on that tangent, but the voltage regulator on the engine is currently unhooked, do I need to eliminate that issue before I worry with OCV?
