Electronics gurus: Need to test whats draining the battery. How many amps do I need to be able to
measure? Looking for a clamp on meter and found one that measures in 10ma increments. Is that enough?

oh and if you happen to know what the resting load on the battery is when the car is shut off and
after run pump is no longer running (with or without an alarm on) that would also help :-)
TIA!
TIA!

I just picked up a few of these...>
For both fuse types. I'd think 10MA might be a little low. Dunno the resting voltage drain though...No car to test!<ul><li><a href="https://forums.audiworld.com/tt/msgs/1611320.phtml">Fuse Buddy tester..</a></li></ul>

Current jumps slightly as door LEDs pulse on.
BTW, you can get a cheap meter from radio shack or Harbor Freight, not rocket science.

can't seem to access the link to the supplier. BUT just picked this up for $20 and looks like it'll
do the trick. Thanks :-)<ul><li><a href="http://huapu.en.alibaba.com/product/50349209/200231382/Digital_AC_DC_Power_Clamp_Multimeters/HP6051_3_1_2_DIGITAL_Three_Phase_Live_Wire_Identif .html">Clamp Meter.</a></li></ul>

That meter is for ac current not dc so it won't work but >>>
for the types of current you will be dealing with when measuring parasitic current drain with with the car off, a regular multimeter with a 10/20 amp range will work fine. You would just need to disconnect the positive battery terminal and connect the meter in series with one probe on the battery and one on the positive terminal.
