[sdiy] SCI Pro One 15+ power rail

[Csaba Zvekan]

Hi Guys,

I'm troubleshooting a SCI Pro One and have a problem with the 15+ power rail as I'm measuring the voltage regulator 7815. I get a value of  -0.6V on a positive rail.
Does that mean I'm having a short of some sort on the many OP-Amps and CEM's etc that tap in that rail ? Any help or suggestion on how I should continue to troubleshoot would be  greatly appreciated.

Thanks

Csaba
