After getting the new 318 tuned up I checked the battery voltage while running and it was between 15 and 16 volts. Just to rule it out I tried a new voltage regulator and it didn't change. What should I look for? Car is a 1971 Dart Swinger.
Just so you know, when the regulator see's low voltage at it's blue wire it compensates for that by overcharging.
The blue wire ties into the harness at what they call a "welded splice" to sense the system voltage, so if there is a crappy connection there it can cause what is happening.
This is why some of us remove that blue wire from the welded splice and route it direct to the battery + at the solenoid using a relay.
This also can sometimes solve the jumpy amp meter needle that some have.
