Continuity Beeps Everywhere? Troubleshooter

If everything beeps, something is joining it all together.

Only test continuity with the power off and disconnected. Work through one question at a time. You can go back or start over whenever you like.

Safety: this troubleshooter is general information for low-voltage DC learning circuits. 240V AC mains can kill: in Australia, work on mains wiring must be done by a licensed electrician. Disconnect power before you touch wiring.
