Hello, all. Apologies for the basic question and/or if this question has already been asked.
I'm the brand new owner of a 1965 R69S. Battery is fully charged and properly connected. I fully insert the key but can't get the headlight to operate or the green or red indicator light to turn on, regardless of whether I have the key turned to the left or right or left in the center.
Any tips? I have the feeling that the key isn't initiating contact with something in the ignition mechanism.

Thank you!
Jason

check that you have battery voltage into the ignition switch (the large brown and red wires on the switch in front of the switch board
If so then the switch is not making contact when the key is pushed in and needs adjustment
With the key in you will see the contact is moved downward and should make a connection
If you take your finger and move it down a little more your red and green lights should come on
If so bend the lower contact point up a little so it does when the key is in the down position and the lights go out when the key is removed

Yes

Yes, the 'points' are not likely opening up when you push in the key. You will be easily able to observe this with the headlight out. Check that you have continuity with the key out, and no continuity with the key down.

Make sure a PO hasn’t

Make sure a PO hasn’t installed an in line fuse that has blown and that you are getting power to the ignition switch.

My thanks to Tommy and the

My thanks to Tommy and the others who responded to my message from earlier. I really appreciate your assistance and patience with a motorcycle newbie. Great community here, and I'm proud to be a part of it.

1. Installed a new battery that is registering about 6.4V when tested with my multimeter.
2. However, absolutely no voltage is registering when I test the wires coming out of the battery either with my multimeter (positive lead on the positive wire, negative lead on the negative terminal or on the chassis). Also no voltage when I test the wires inside the opened headlight body, including the large red and brown wires per Tommy's recommendations.
3. I did take a look at the ignition switch and made a small adjustment to ensure full contact when the key is fully inserted and no contact when the key is half or fully removed.
4. Although the battery is new and as noted above registering about 6.4V, there is quite a bit of corrosion on the positive terminal. I've cleaned, applied protectant, but same issues as noted above.
5. No red or green light (or any power to lights, horn, etc.) when bike is in neutral, key fully inserted, contact on the ignition switch confirmed, and key either left in the center or turned to the left or the right.
6. Also no luck getting the bike to start without the battery, though I'm ticking the carburetors, opening the throttle 1/4th, key inserted and left in the center, one full, gentle kick to turn the engine, and then some strong kicks to follow.

There are better people at DC

There are better people at DC systems than me. But I was wondering if you have 6v measured at terminal 51 on the headlight circuit board. Terminal 51 is essentially direct to the battery + terminal routed through the generator. If you can't confirm 6v there, then you have to get that resolved.

As mentioned before, is there

As mentioned before, is there an inline fuse between the battery and headlight bucket?

You also may have a bad ground
Pic of wiring diagram below
As Kurt says the battery positve + wire from the battery goes directly to #30 or #51 on the generator(they are tied together)

I would put your negative lead on your voltmeter directly to battery negative and then the positive lead on your voltmeter to the 2 large wires on the generator #30,#51 (should both be large red or could be large red and black)
If you have voltage their then put you negative lead to anywhere on the engine case and see if you are reading battery voltage
If not battery negative from battery is not grounded to the engine frame
also as noted someone may have added a fuse you should be able to see it on either battery lead on the battery or maybe inside the generator assy or inside the headlight shell

I would sort out the electrical problem 1st although this electrical issue should not prevent it from starting
