Default Alternator charger problem
I'm having trouble with my battery going dead when head lights and fans are running. I have a high output alternator that seems to be working. If you measure voltage at the alternator, it is putting out 14.2 volts with fan and headlights on. If you measure voltage at the battery it is only showing 12.4 volts. I was driving at night for about 40 minutes with these things on and when I stopped for gas the battery was dead. Checked battery and it seems OK but is three years old.

Any one have a clue what to look for?

Thanks,
Rick
