Motorcycle Repair: honda cb 360, honda cb 360, rectifier

Question
a while back i got a 1974 CB 360 out of a barn. I've been working on it but gave up a while ago because i cant get spark. I've been told i need a selenium rectifier, there isn't one under the seat like there should be. i researched and found that Honda used a kind of alternator to charge the battery and that powers the spark. i need to know how this works and what to do to make it work. this is my first motorcycle project and I'm a little lost, I'm good with cars but i don't understand how its supposed to be, any help would be appreciated, thanks.

Devin, the rectifier won't prevent power to the coils. It just won't charge the battery if it's missing.  The alternator puts out 3 phase alternating current and the rectifier converts that AC current to DC current.  There's a voltage regulator that maintains the output to 13.5-14.5 volts. As long as the battery is charged, the bike will run.  The power to the coils comes from the battery to the ignition switch to the RH handlebar switch and then to the coils.  It's the black  and white wire.  The coils are grounded through the points.  I'd start by making sure the coils have power to them and then make sure the points are grounding that circuit.
