Hi All,

Newer battery dies overnight. Charge it for a short bit & it starts right up & continues to start up all day. No clock & dummy gauges. Glove box, courtesy lights & trunk light all turn off & remain off. Alternator appears to be functioning properly. Recently rebuilt 327, 400 trans. Any ideas?

Thanks for the helpful link. It appears that the voltage regulator is the culprit. Will replace & see what happens.

After further testing it turns out it's actually a bad diode in the alternator.
