Hey Thor - here's a few things to get you started:

1 - The two unused terminals (#1 and #2) on the alternator. Are the spade terminals in line like this: - -, or are they parallel like this | |? If they are inline it says you've got an internally regulated alternator. And the rubber plug indicates it's probably a so-called "one wire" unit - the plug is there to cover up the two unused terminals. If that's indeed the case, the alternator should charge once the motor's been up to close to full RPM. Once the alternator starts charging, it'll continue to charge all the way down to idle. Regarding the voltage regulator, presuming it's for the original generator (has 4 terminals labelled B, G, F and L) you can get rid of it.

2 - A couple ways to check the coil: Look and see if it's stamped "12 volt" someplace. Or you can turn on the ignition (don't start the motor) and look at the ammeter. If the meter shows 3 or 4 amps discharge, the coil's a 12 volt. If it draws 6 amps or more, it's a 6 volt coil. Or you can feel the coil after the motor has been running for 10 - 15 minutes. If it's just slightly warm it's a 12 volt. If it gets real hot to the touch, it's 6 volt. If you find you have a 6 volt coil, stick a ballast resistor in series with the coil, or replace it with a 12 volt coil - otherwise you'll burn up the points and/or the coil.

Hope this helps!
