'99 Contour electrical problem/speedometer
Daughter's car. She says that the speedometer quick working one evening. Next day the car quit, the battery was drained. Thought it was the alternator since battery volts didn't increase when vehicle was started, dropped from 12.7 volts to 12.3 volts. Changed alternator but same results. Can start car and remove ground from battery and car quits. I have checked various things, fuses and wires to alternator from battery. I have replaced the battery and alternator with no luck. Not sure if the speedometer not working has anything to do with battery being drained????? Have also changed the speed sensor in attempt to fix speedometer but no luck. Any ideas??????
