Battery Still Draining?!?
OK....I have a parasitic battery drain. I have a brand new battery that will go through the entire charge overnight
I have my #8 fuse disconnected (radio)....and I disconnected my alarm all night, woke up...dead again (its not the alarm)
Here is a pic of what I am doing to test it:
is .15 or 150 millaamps too much? Am I reading this right?
Because no matter what fuse I pull, it remains constant at .15 or .16......HELP!!

hmm, that shouldn't be enough to completely drain it overnight.

What are the normaloperating ranges?How much should a parasitic drain be showing??

Check this out...
When I put a test light in a series with the negative battery cable, I am getting a faint pulsating (constant) light...........any ideas?

you don't have any aftermarket component that is tapped off the selonoid always hot side or the battery do you?? reason asking is this would bypass the fuse box..also when running the test you have the under hood lamp disconnected right?? and all doors and trunk shut??

All doors and trunk are shut, hoodlight disconnected.The only aftermarket thing hanging off my solenoid is my MSD6al Box. I tried to take it off and no change.
I have my Stereo Amps off the battery, but I pulled them off too....nothing [:@]

I think I see your prob!!!!! you have it set on the milliamp function!!! testing for a drain I learned the hard way to never use the milliamp function cause anything over 400 milliamp drain at least on my blue point meter it pops the fuse!! use the yellow setting that says 10 amp below!! this will handle a large drain and help you find the prob!! restest everything using the amp function on the meter and remember to move the decmil point to read amp drain correctly

RE: Battery Still Draining?!?
I shot you another PM.....but I think I am reading it right 
The issue was, when I set it to the 10Asetting, as soon as I touch the terminal, my alarm went off. I naturally thought this was too much power going through the multimeter....
This time, I took your advice, and when the alarm went off, I disarmed it and held it on the battery.....now it will fluctuate up and down as I turn things on/off.....
A quick summary:
Normal load was 3.35 or 33.5
Turned the headlights on, and it jumped to 7.25 or 72.5
Unplugged the Alternator and it dropped from 3.35 to .015, or 1.5........I think that is the problem
THANK YOU!!!!!!!!!!
Next question is, which alternator to get?!?
