Power supply no -15 Volt ground

Discuss Yocto construction and related issues
  • Check IC5 if it is soldered properly and also check diode orientation as well. IC5 is a 7915 negative voltage regulator. Start with that.
  • The Diode orientation works alright like you can see on the board. And the Diodes are working like they Seouls. How can i check the ic5 or do I need a new one? Thanks for answering
  • Probably using a DC wall wart. You need one with an AC output.
  • Good point "ikke"
    Sud76137 did you check your power supply is it 15V AC or is it 15v DC it should be AC.
