I recently worked on my grandma's 92 mercury cougar and found the battery dead, jump started it and it ran for about a minute or two and died. I replaced the alternator and plug, and had the battery tested, it was bad also and replaced it as well. After the new battery I checked the voltage and it was still only charging at 12.3 volts. What else could be wrong besides the new alternator possibly being bad? What else should I be checking?
have the same problem?
