Overcharging 68Dart...need some short fused help (pun intended:)

I finally got back to it today.

I reinstalled the NAPA VR-32 style regulator grounded very well, and sense line (batt) through a relay.

I found what blew the 30A fuse, the aftermarket stereo I installed shorted out internally due to the high input voltage it was subjected to and blew its 10 A fuse. When I installed a new fuse, in ACC position it was pulling 20A (with it out, less than 1A.)

Question for you, is 5A normal draw by the coil in the ON key position (not running)?
It’s less than 1A with the distributor disconnected from the coil.

I cut the battery terminal off in case there was corrosion buried in there and I’m replacing it and the line to the starter relay. After that I’ll take some readings with the car running.

Thank You again for all your help!
