A permanent magnet alternator isn't going to suddenly produce 1.5 times the voltage it was wound to produce. NOT gonna happen.
It's possible your (digital???) meter is confused by the waveform it is "seeing", or freaked out from ignition system "noise".
Connect the wires back up to the rectifier/regulator, and measure again.
Then check the DC voltage reading on the rectifier/regulator's third/output terminal.
Also, the "case" of the rectifier/regulator must be grounded, it mounts to sheet metal, and problems with grounding have occurred. The system can't produce charging current without a good ground there.
If it doesn't already have one, run a ground wire from one of the rectifier/regulator mounting bolts to a GOOD ground.
