Re: GROUND SHORTING

Before I try answering your question, what is the reason for shorting both the power supplies??? I have heard about shorting the grounds.

I guess you are trying to short the grounds of +5V and +24V together, then the best place for your to short them is at the power supply entry point. Short by means of a ferrite or find out whats the resonant frequency and short the planes together with a capacitor whose frequency of operation matches the resonant frequency.
