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!! |

Thanks so much! Great directions. I will test out.
I have a strong feeling my 2 amps are always drawing power- even when car is turned off. Are amps supposed to be wired in some 'special' way that they stop drawing from battery when car is off? Is there any way to tell if they are wired that way currently? |
