overcharging

Like what?

There are hundreds of threads on this subject

1......Voltage drop in the harness

2......Poor grounding on the voltage regulator

3......Fairly UN common, bad battery / going bad

4.....Bad voltage regulator

Notice the regulator is at the BOTTOM of the list




#2 for me. I replaced the original point style with a electronic regulator in my 66 Dart and boiled the battery and blew light bulbs. Bad ground for the regulator at the firewall. tmm
