Parasitic Drain Test When checking for parasitic drain, do you hook the multimeter up in series (disconnect battery) between the negative battery cable and the negative battery post? What is an acceptable number of amps for just a clifford concept 100 (nothing fancy). I'm not having an issue, but I just received a new digital multimater and am curious. Thanks!
Yes...you just hook it up in series. I had to make sure I used the larger fused port on my multimeter since my car liked to spike upwards of about 1 amp after the initial connection, and then it settled right back down to where it should be (I think mine draws 10-15 mA after everything settles down). The spike was blowing the smaller fuse in the other port though...

I hoooked up in series between the negative battery terminal and it pulled about 0.01 amps with no alarm. When arming, the amps shot up to 5-8 amps and then went back down to 0.01 - 0.03 amps - kept cycling. I didn't use milliamps since I was fearing blowing a fuse when arming the alarm (5,000 to 8,000 milliamps exceeds my mA options during the arming). Thanks for the tips.
