I have a 65 Coronet that I recently bought and I am trying to sort out my last issue with it. I put on a set of dual electric fans and 26 inch radiator to keep it cool and settled that issue. My first night out with it the voltage regulator went out. It had a stock type points regulator on it. Right now it has a square back parts store alternator on it. I switched to a stock looking electronic voltage regulator yesterday and it is charging again, KINDA. It is only showing around 12.6-12.8 at the battery at idle, if I rev it up it goes up to 14.3-14.5 but right back down at idle. This is with the fans off. I have a new Power Master 17509 75 amp alternator to put on it but am I going to accomplish anything by doing this. Power master instructions also show to ground the extra field terminal. Right now I just want to get out and drive before the season is up but 12-8 volts without the fans on is not going to cut it. I guess my questions are.
Do I need to install a 1 wire alternator with internal regulator.
Do I need to use the one I have and ground the extra field wire.
Do I need to run a 8 gauge wire directly to the battery.
