I took a one wire alternator to Advance Discount one time to be tested and they didn't know how to hook it up to their machine. They had plugs for every other alternator setup, but not one wire. So, you might run into that.

If you have a dash voltmeter, simply turn on the key and note the voltage. If it reads 10.5 or more it should crank. If you get it started, bring the rpms up a little and the voltmeter should rise to almost 14 volts or thereabouts.
