Engine Mechanical problem
1997 Mercury Sable 6 cyl Two Wheel Drive Automatic 134000 miles
Put new alternator and new battery but alternator fails to charge battery. Tested alternator wires at alternator and all were good. Checked the output with a voltmeter at battery, numbers started at about 14.2 and continued lowering. Wondering if the ecm completes the charging system or if for any reason could be the problem.
