Hi,
I purchased a Craftsman Digital Multimeter with AC Voltage Detector: http://www.sears.com/sr/javasr/product.do?...0383&AFFL=Y Now, I want to test my car battery to see if there is a draw when its off. I watched someone else do it. I believe he took neg lead off batter. Connected one end of multimeter to battery neg post - then clipped on other end to any part of car. Light was on - which indicated a draw. The light was always on even after pulling fuses out. Is this the correct way to test? Please see the multilmeter I purchased and let me know how you would test for a battery draw. Thanks!! |

well I checked mine today..
it was drawing .2 amps when off I started pulling fuses and wires and found that: Pull Main Fuse - drops .1 amps Pull my UnderCar LED wire - drops .05 amps Pull Capacitor - drops .05 amps.. So I hooked up a switch to the Undercar, and disconnected the cap for now.. but I still don't know what all is drawing the .1 on the main fuse circuit  -------------------- ~Daniel~ No Longer Celica Owner.. moved on to a 03 WRX-EJ207
