I have been thinking of a possibility of converting my 1947 Lincoln Continental still running on 6v to 12v. Can someone advise me what I need to do to carry out this conversion. I have made a plastic base and installed two connectors which give current to rotor from 2 x 6v coils ...it fires up but goes dead immediately .... looking for advice. My car is located far away i Pakistan. It was originally owned by the ex King of Afghanistan, Zahir Shah.
