High voltage Dart -67

Hi there from Sweden
Cant get my head around my voltage problem
I've tried a new regulator and the bulkhead cut wire and a relay
Bought the car off an electrician so everything is a nightmare :D
It has a ready to run distributor and at one point in its life it's had an MSD system witch is off the hook now
The ignition key is some random fits all but really nothing and has
1. Starter
2. Ign
3. Battery
4. Acc
Is it possible to get a normal voltage on this setup or do I need an original ignition key or something else?
Thanks in advance
