Guest magpie9 Posted November 16, 2007 Share Posted November 16, 2007 hey, quick pop quiz. battery's showing -14.4 when running. not a positive 14.4 reading. if the car starts will it draw power on the battery or alternator to get me home! seems to be draining battery!

robin Posted November 16, 2007 Share Posted November 16, 2007 Reverse the leads on the multimeter? Cars run on a 12v negative ground anyway. Quote Link to comment Share on other sites More sharing options...
