Well, actually you are supposed to use look for the amperage draw and unplug things until it drops to an ok level. Using a test light is the old method of doing it. So NOT WRONG...

Exactly, the charger was a parasitic draw, just like I said.

i ment the guy is wrong. i ment to type in correct

if something shorted out the fuse would blow. a short to ground would cause an excess current draw which would go above the rating of the fuse.

Wouldn't the dash clock inside be drawing a tiny bit of current and so when he connected the leads to the negative the light would come on?

depends on what the test light is rated at. Is the test light rated low enough to light up off that small ammount of current?

All cars have an acceptable draw...modules/computers,clocks,radio memory, etc... Test lights used to be an acceptable way of finding a parasitic load because cars didn't have all of that ---- "powered up" all the time. Now that cars have all of this ---- sometimes the acceptable draw will light a test light and you will be searching for a parasitic load when there really isn't one. Which is why I said earlier that the proper way to find a parasitic load is to put an ammeter in line between (-) terminal and (-) wire.
