how to measure / confirm normal power drain?

[1Gina2G]

okay so I'm going through a bad battery issue it seems, working on finding a good optima battery. anyways, I got a new test light that works, connected the clip to the negative post with the positive still atached, and I get the tiniest, dim light , on any of the ground cables, it's next to no light, so I'd like to assume this is the normal power drain.

Is there a way to measure / confirm normal power draw? With volts, i get 12volts no matter what it seems when i measure for voltage the same way I used the test light, probing between negative post and ground wires.

anyone set on any specific battery brands by chance? I'd like to get a known quality battery haha.
thanks everyone!

The red top Optima battery is pretty good
But I have the red dura last on mine and Ive left the system on for 4 hours and it hasn't died

Try a multimeter (on current scale) in series with the neg battery post: http://www.dsmtuners.com/forums/art...-partial-short-battery-drain.html#post1496998. A factory car will not draw more than 50 mA.
