ok, so I checked the ramps board a little more. for some reason i'm getting 10v on 1 leg of the bed heater connector and 12 on the other? seems odd then again i haven't told the unit to heat the bed so perhaps that's not unusual. I disconnected absolutely everything and get the same result. Fuses are good. Checked the voltage at the stepper drivers when the 12v power is on and the .5 volts that it should be getting is there. once i'm at work tommorow i can get a schematic of the ramps board and begin checking it out in detail. I believe the ramps board is the culprit
