Battery draining fast

The regulator does have a stripped screw I'm going to run a wire from the ground (aftermarket) wire to the firewall and replace the screws on the regulator and pigtail a self tapping screw to the same wire with ring connectors. I'll let you know what happens .
DD is beating me up over this its her first Car and she just want to drive it . I've restored an old Falcon and Chevy Truck and I've worked as a residential electrician ,butI've got to say these plymouths are very tricky trying to figure out !!!
Thanks again for your input gentleman ,
