Electrical problem
1995 Ford Aerostar 4 cyl Two Wheel Drive Automatic 242,00 miles
----------------------------------------------------------------
i have replaced the battery, alternator (2) times, and the voltage regulator. the alternator is not holding a charge. the battery is drained in no time. my husband changed the ignition switch and that's when the problem started. there is also a short in the light switch. he said he checked the fusable links and they were fine. what could the problem be?
