Question a few months ago i had a starting problem on my 1998 ford expedition 5.4 liter. we would hear a click when we tried to start it. so i would charge the battery with the bettery charger but the bettery was still good so i just jumped it and it started. we changed the positive wire to the starter (battery wire) we had the stator rebuilt twice, and we changed the battery to a much better one cause a guy said if you got a cheap battery it will mess up the stator. so now we had a new stator, cables and duralast battery and alternator. the car starts now but the battery is draining. we keep starting it and it reads out 14.4 on the tester. so we waited to next day and the battery read 12.0 flat/low this battery/aternator tester. the only thing i know is wrong with the car is that we have (on passenger side) sidemarker light fell off and maybe the harness might get shorted out or something.. please if you can help it will be a real good help cause i got nothing!!!
Answer hey there, there is one other quick test that i notice you hav not listed, you have to check the amperage that the altenator is putting out, you should be between 20- 30 amps at idle with no accesories turned on. do this and get back to me good luck
