No spark :(
Well, I have no idea what's left to test.
I have new points, new condenser, new plugs, new plug boots... I had the coil tested and they said it wasn't shorted (couldn't test it under load as their machine was broken I guess). What the heck else could it be??? I've tried every key position too.

How are you testing the spark? Have a tool or you just putting the plug next to the cylinder and spinning it without the spark plug in it? Your battery is getting a good 6V reading right? The ground strap on the battery getting a good contact on bare metal? Also your rectifier look ok? I've heard these could burn out if you don't use a battery and try to ride it around but that's just hear-say. Check your connectors again and use a volt-meter to check and make sure you are getting continuity through them all. Wiggle them a little when you have the tester on it to make sure it's not some intermittent connection.
You should just put the key in the ignition and you only need to go one click to turn it on/ to get spark. The spark should be obvious and make a snapping noise... as I'm sure you know, just sayin.

Do I have to have a battery to get spark? I don't have one connected yet.
All my other connections are fine. I'm using a spark tester. It looks like a spark plug but has a spiked jaw on it that you clamp to the cylinder fins.

Well, just installed my new 6v battery that I bought for this bike and I still have no spark... but the plot thickens.
I have no power to anything. No horn, no lights, nothing. The cable doesn't even spark when I touch it to the battery. There are two positive battery cables... one just for the starter solenoid and one for the harness. I tried both individually with no result. The ground is nice and tight to the block/frame mount. I tested the tail and headlight separately and both work. I pulled the headlight and checked all the wires... nothing looks touched and all is tight. Checked all the wiring behind the battery. Removed the coil and starter solenoid... all connections are fine. Checked and even bypassed the only fuse on the bike with no change. I guess this bike need the entire wiring harness removed and checked over; something I'm not willing to do. I might just sell this project I guess. Or use it as a parts bike, I don't know.

Hold your horses! I have a couple things you should check. I'll get pictures of a couple key areas that you can look at in case you might have some exposed areas in the wires. I'll post when I get it together for you soon. If things are screwy like you say I would suspect a connection with the combination switch (key switch). Check to see if there are any wires worn down where they extend from the frame to the front headlight.
You think this might be the problem with the bike why it was put away? Every classic Honda I have seen was put away back in the day because something broke and the owner didn't want to fix it.

Received a -mint- original (1965 date code) wiring harness from ebay for $16.
Gutted my wiring harness. Mounted the coil and rectifier outside the bike (so they would be grounded if that's even necessary). Hooked my battery up. Now, on certain key positions, the electric starter button turns the motor over. Still no power to lights, horn, and no spark. Beginning to want to give up here!

Did you check to make sure the fuse isn't blown and that you get current from before and after it right? I've had it blow on me before and the bike will just come to a stop. It will only blow if you have a short somewhere. Even it the fuse is good make sure that power is getting to where that wire ends up going at the end of it.

The harness I just got has no provisions for a fuse. No evidence of wires being cut either so I know it's factory.
The harness I pulled from my bike (date code 1963) has a fuse, and it is good. Just in case the contacts were bad I bypassed the fuse; no change.

Well, except for the stuff inside the motor I've checked all the electrics.
I'm not sure how to check the rectifier, but when I test each of the 3 contacts against ground one has 6.1v (same as the battery) and the other two are around 1.6v or so. What I need to do is find someone with a running bike and offer to loan me parts so I can troubleshoot! Anyone? Anyone?
