The alternator makes the power and it is regulated by the voltage regulator.
If the contacts stick closed in the V regulator then the alternator has no governor to control it when running. It will max it's self out and this is why you have 17-18 + volts.

Just some food for though.
A 1 wire alternator will work but it want have the capability to control the charge like the 3 wire.
A 1 wire will charge at the same amount no matter what the load is on the battery are the rpm of the motor, where a 3 wire will only charge at a rate enough to keep the battery at a constant charge so it want ever under charge it are over charge it.
