Are there tests that prove electrical connections are working satisfactory.


I ain't no expert on this kinda thing but I seem to be able to hack my way through rudimentary electrical problems at least. In many cases, a continuity test can help with electrical issues (such as the integrity of connections). And so I quote from Wikipedia the following...

"In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path. If electron flow is inhibited by broken conductors, damaged components, or excessive resistance, the circuit is "open".

Devices that can be used to perform continuity tests include multimeters which measure current and specialized continuity testers which are cheaper, more basic devices, generally with a simple light bulb that lights up when current flows."
