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!! |
