Charging Issues,

Hi,

Okay, it seems the alternator is alright and it is a regulator issue. Either the new regulator is defective or it is not grounded. Bad grounding is quite common. You have 50 year-old half stripped out, rusty sheet metal mounting screws on many old cars. Make sure the metal on the firewall under the regulator mountings is clean and shiny. Also, make sure the screws can be tightened well and use an internal or external tooth lock washer under each screw head. That should take care of the ground issue. If it still doesn't work the regulator is likely defective. With today's quality level on new parts it happens more than you would think.

Good luck and let us know how things go.
