Test light!
stupid simple tool that has served me so long.

While those from Snap-On cost a king's ransom, I have one that's been around for almost thirty years. Now, of course, they have all manner of uber-cool test lights to indicate polarity, voltage level, presence/absence of current, etc.

If you're too cheap to buy one, they are easy enough to make.

Another tool I use often is a cigarette lighter plug with stripped wire ends. Provides a known good source of both +12VDC and -12 VDC and the ability to have a known good ground while using the test light is pretty indispensible.
