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!! |

Battery is brand new. Probably less than 1 month before car began dying.
Alternator has been replaced 3x already. Alternators are all rebuilds though from R&S strauss. I wonder if the alternators are no good. Well, both Ill have him see if there is a draw while car is on. My private mechanic said no draw on battery while car is on. Another note to mention is when they installed the alternator, the harness attached had to be re-wired or reset to make it connect. I wonder if that wiring job is faulty. |
