I was trying again to see if I had any current draw so did some internet sleuthing to help me figure this out. I can rebuild engines fine, tune motorcycles, etc, etc, but when it comes to multimeters I am an idiot. I think I did it right, but want some backup on this. I put my MM between the + terminal on my new battery and the + cable. I then set my RadioShack MM to the notch marked 200 DCmA which also had a solid line beside it with 3 dots under it. I then took the reading, and it said 00.0 ??? I reversed the leads and it then said -00.0   
Does that mean I have no current draw at all?? I am lost, because I have a small digital volt gauge plugged into the lighter that MUST be drawing something??
 The MM reads voltage across the battery fine, at 12.74volts, so I think it's working fine. What am I doing wrong??
