Hi all
With mains applied , i can hear 1 relay click , then a second or so later a second click .
3.3 volt supplies stable .
The 36 volts supply rises , then falls away , after second relay click .
Cannot find any faulty electrolytic capacitors .
Also spent ages removing that glue manufacturers like to use , that becomes hard & corrosive .
No obvious short circuit reading .
