Chrysler Repair: 93 New Yorker Battery drags in 3 days, chrysler new yorker, resistance one

Question
Hi
My 93 Chrysler New Yorker runs fine and everything works, but if I let it set for 3 days something pulls the battery down and I have to put a charge on it. This is the second new battery I have tried.  What could be causing this?

Answer
Hi Neeka,
Chances are that one of the interior lights is on all the time (glove box, under the hood, in the trunk). So look carefully to see whether those bulbs are truly going off.
The other approach is to use an ohmmeter to measure the resistance that each of the fuses is supplying current to.
Here is how I told a '94 New Yorker owner to look for the circuit that was dragging done the battery:
"If you can get a hold of a volt-ohmmeter with a digital readout you could differentiate a low but finite resistance from a high resistance. One of the fuses is supplying power to a circuit with a low resistance and that is why the battery is running down.  The upper pin socket is the hot side which has 12V on it from the battery, so don't touch that one. The lower pin  is the one that is 'cold '(i.e. all the lamps and devices are attached to that one). If you set the meter to read ohms (20 ohm full scale) and touch the - lead  of the meter to a shiny metal body surface and the + lead to the lower pin of the fuse socket it should read more than 1 ohm, the more the better.
Now the question is how to find which of the many items that are suspect is causing such a low reading. .
So go thru the fuse box to find a fuse whose cold side reads less that 1 ohm, and let me know which one(s) it is.
Then we can for on from there to isolate what component on that fuse is drawing the current".
