A 12 volt draw on battery from a one wire alternator

Well darn ran a wire from alternator to starter relay with 30 amp fuse. I left the wire running to ammeter alone. Ran another field wire to the ignition wire on voltage regulator. Tried testing it as recommended by voltage regulator instructions by leaving it unplugged and running test lead from green connector pin start car and then ground test lead. Now car tries to start but wont fire.
