Yeah I'm not sure how to test the voltage at J1 as i'm getting 11 volts at the first two pins. That's with all three connectors and power on. I think the fact that I don't get -12v at far right pin of J2 is a worry. A startup video I watched mentioned that but didn't say what would be the cause. My power supply board was rebuilt in November 2015 and the machine is an Australian Delivered one.
