12 Volt DC Power Bus Management
The other night I was working on the layout connecting a device to the 12 volt DC power bus I have on my new layout. Soon I smelled something electrical over heating. I immediately shut'er down. I knew where the problem was and was able to fix it easily. Then I began to think that there needs to be a over load/short circuit protector. I have my track power fully protected but not my 12 volt DC Bus. I thought of putting a automobile light in series in the circuit which will "light up" if too much current is being drawn through the circuit. Then I remembered I had a DC Amp meter laying around too. So I designed a 12 Volt DC Power Management panel with a power switch, amp meter, and an current over draw/short circuit light.
