" thx for starting the wiring diagram "

____ I had had expectations that you'd include mentioning what-all you've noticed as being the three major/noteworthy changes made for the latest diagram-version. _ But I'll go-ahead & review them now, anyhow.
Firstly, you should've noticed the added 4th pilot-lamp (that's easily circuited to the parking-lamp [and labeled 'Green']).
Then next, the horn-circuit is now shown with the most efficient (non-relay) power-circuit which allows for battery-power to rather directly feed your high-power horn's strong demand for high-amperage current, (as well as allow for an always hot horn-button).
Then lastly,, since the previously dedicated horn-fuse would've been left purposeless, it's now shown to be dedicated rather to the rear brake-light switch. _ This fuse-circuit change comes along with a pretty-sensible advantage ! ...
By having the front & rear brake-switches rather separately fused,, then in the event that a short-circuit ever develop some-where in the brake-light circuitry, the source of the 'short' can then be much more easily traced-down ! _ Cuz if only just-one of the brake-light fuses blows, you then already know that the short-circuit is only possibly located just within merely that fuse's power-line (to it's-own associated b.switch), alone ! _ And, if both front and rear brake-fuses get blown,, you then already know that the 'short' must thus-then be located within the common-line that connects both brake-switches to the taillight !
So this double-fuse setup (for the two brake-light switches) can cut-down any short-tracing trouble-shooting effort, by (roughly) two-thirds !



" that thing is the on worrisome part of the rebuild, "

____ So long as the likes of myself is able to assist guiding you,, not-only should you not be so-concerned, but-also it's pretty-likely that you'll find your wiring-work to be an enjoyable experience and perhaps your most proud project-achievement as well !



" I'm now sure there are only 2 original warning lights on my headlamp. "

____ Hopefully someone-else with a pre'66-Monza, will clear-up which pilot-lamps are present on a stock 150mm.headlamp, (and also mention each one's individual location atop the HL.shell).



" I'm thinking about your other suggestions! "

____ Concerning my last one,, you ought realize how having the high-beam light-up along-with the sound of the horn, would desirably increase the intended warning-alert of the horn alone.
Thing-is however, such tandem functions require a diode/circuit-valve to prevent complete mixing of the involved paired-up circuits. _ So that would mean additional wiring details to complete (which you may not really wish to become concerned with).


Fun-Cheers,

So far as I can ascertain, the two lamps should be - green (top center) and red(left side). The third small opening on the right side being the key switch.
As far as function....I'll have to stare into the spaghetti diagrams, wire by wire.
Both of my aprilia 150 buckets were stripped when in found them.
Hope it helps a little.

____ Thanks for your response-post Travis !

" the two lamps should be - green (top center) and red(left side). "

____ When you state that the green-one should be "top center",, I don't out-rightly disagree but, more specifically, I recall it being located about 15~25mm behind the rim-seam, as well.



" The third small opening on the right side being the key switch. "

____ That seems correct to me, also.
So if there's not still another hole as well,, then either the high-beam indicator was-not included, or-else there was never any lamp-lens for the charge-circuit light-bulb to glow through, (which would make less sense, since the charge-indicator circuit and it's light-bulb were indeed included [as is indicated in the below posted pre'66 Monza electrical-scheme diagram] !).
So if the red-lamp doesn't include it's-own built-in light-bulb (like a std.high-bean indicator-lamp must have), then the red-lamp's lens must've been intended for the remote light emitted from the charge-indicator circuit's (rather independent) light-bulb.
__ I've now updated this post to include an overblown-up (thus fuzzy-looking) view of the red-colored lens (with it's holder) that flanker had previously presented (along-with other pilot-lamp versions). _ And it's of the pilot-lamp type that doesn't include it's-own internally-fitted light-bulb, so it must be intended for the charge-indicator function (rather than the high-beam indicator-function).

Bob, I've just had a good look at the diagram with "play by play, side by side" comparison with an iPad with the pic and a computer with your explanation. It all seems sensible! I like the dedicated fuse on the brake light. perfect sense.

Questions (which are probably obvious to many):

1. where is the relay physically? In the head lamp, under the seat?

2. What do the rectangular black boxes signify? for instance under the stop/tail light.

3. Im not going to include a front brake switch which I'm still a little concerned about.... but i'll get over it, so I have to omit the "front brake light switch" from the diagram?

Just finished rebuilding my shocks, see below its a silver special. They look even better in the sun. Powder coded in compton. Chromed in gardena, these guys were so cool. They have a huge collection of pre 1940's bicycles, surfboards and hot rods. Plus they surfed with all these guys in venice that I know under the now gone famous POP pier circa 1935. Cheers Rob

____ It's too-bad that when posted pictures are clicked-on for getting the full-sized view of the minimized-version that's seen within a post, that the mini-version's included captioned-wording then becomes left-out of view (on the opened expanded-view page).
__ For those who don't happen to have two separate means to keep both views simultaneously viewable side-by-side, ya could rather copy the mini-version/posted-picture's caption-wording (or it's entire post) over to a WordPad page and-then keep it displayed on your PC.screen along-with the full-sized diagram.
____ Have you ever yet printed-out any of the posted diagrams for off-line viewing at home (or out in your garage or wherever) ?



" where is the relay physically? In the head lamp, under the seat? "

____ Assuming you're referring-to the relay-unit intended for the ign.circuit,, it's been my intended inclination for it to be included within the headlamp, (thus not far from the key-switch). _ However, you're of-course free to locate it wherever you see-fit to prefer wiring it up at.



" What do the rectangular black boxes signify? for instance under the stop/tail light. "

____ I don't see any "boxes" of any shape or color "under" the tail-lamp. _ However if you mean all the black-rectangles included at various places inline with many of the wire-lines,, I-myself assume that Mr.Blackie had intended them to represent terminal-connections between the bike's-own main-wiring and the permanently-attached pigtail-wires of all the various individual connected components.
__ I further assume that Blackie's use of both black-colored rectangular and round-dot wiring connection-points,, are meant to signify whether the connection-points are wire-terminals of a component-pigtail, or a rather independent manually added wiring terminal-connection (made by the wiring installer) (as represented by black-dots where wire-lines meet).



" Im not going to include a front brake switch which I'm still a little concerned about.... "

____ You can always add that function later (sometime after you've completed all your priority works).


" so I have to omit the "front brake light switch" from the diagram? "

____ Not really, just simply ignore that minor section of the wiring-scheme (until you need it).



" They look even better in the sun. "

____ Indeed quite nice !



" Chromed in gardena, "

____ So you really had all the alum.alloy pieces actually chrome-plated ?


Hopeful-Cheers,

That makes sense they are terminals.... Thx for clarification

I was planning on the headlamp of the relay, but I wanted to make sure.

Im going to get the diagram printed in color, but my printer is poor. I'll take it to Staples.

Yet your right, I should of said chromed and polished in gardena, but I was really psyched at how they came out!

Planning on visiting the painter on Friday, so I will have a pic of the headlamp and bulbs after that! This bike is gonna look so good! I hope that electrex will function well. I have the points and a new regulater/rectifier as a back up though!!! There have been a lot of conflicting reviews of the electrex. cheers Rob

" That makes sense they are terminals.... "

____ Whenever I-myself draw-up schematic-diagrams, I don't bother to include such rectangular terminal-connections unless it's important to indicate that a particular load-component includes it's-own pigtail-wire that's separable from the connected main-wiring.
__ When I properly finalize the master-diagram which completely reflects Ducati's n-c.wiring color-code, I'll then remove any such unnecessary (and possibly misleading) terminal-connections.



" Im going to get the diagram printed in color,
I'll take it to Staples. "

____ How were you expecting to be able to do that exactly,, by downloading the posted diagram-pic to a flash-drive and-then take it to them to print-out it's image onto a paper-sheet for you, or what ?
__ If so, and it's not done free of cost,, then you may as well wait until I've completed a finalized master-diagram.



" I should of said chromed and polished "

____ What my related question was really intending to get-at, is the concern of chrome-plating those alum.alloy parts ! _ As it's my ('70s era) understanding that std.type chrome-plating can't be trusted to remain adhered directly to most any alum.alloy surface.
__ Or am I now supposed to understand that you've rather had the original surfaces super-polished to make it appear as "chromed" ?



" I hope that electrex will function well.
There have been a lot of conflicting reviews of the electrex. "

____ If such readily existed back in the '70s, I'd then likely know as much about it as anyone-else,, but unfortunately I never got my hands on the-like before I dropped-out of the DUCATI-seen back in the early '90s (due-to becoming disabled with severe-RA).
__ While I would've been personally very interested in installing such an aftermarket-system on one of my-own Dukes sometime well before the '90s, I've since become far-more loyal to retention the stock DUCATI alternators !
However, I'm still inclined to see the stock ign.points setup replaced with most-any updated substitute ign.trigger-system.



" I have the points and a new regulater/rectifier as a back up though!!! "

____ When you stated "new regulater/rectifier", do you mean a 'stock' DUCATI black-box as like originally employed on the n-c.Monza-models ?

Who was the chrome plater in Gardena you used? Matt.

[flanker]

Matt it was Vernes. Its 4-5 streets west of EL Segundo and the 110 intersection. Cheers Rob
