____ First I must say that you've drawn-up a quite nicely done schematic-diagram, (although it's 'scheme' isn't the best) !
Thank you. At least it looks good, as for the content, it's a work-in-progress.
__ There's a couple concerns with your wiring-scheme needing to be addressed...
First,, is that your horn-button/switch, (assuming will be handlebar-mounted), needs to be repositioned on the ground-side of the horn.
For a normally-off switch? Why is that?
Next,, was this scheme of yours conceived before I posted concerns about your weak-spark with your Jap.ignition-coil ? _ Cuz your scheme shows the ign.coil wired-up as if rather within a battery-powered ign.circuit-type ! _ Yet I had expected that you've understood my post concerning the particular way that Ducati's magneto-type ign.circuit is actually connected-up.
So is this aspect-point of your drawing an ERROR, or did you find that your ign.coil's resulted ign.spark started better with this indicated ign.coil-connection ?
Does this drawing of yours presently correctly-represent your chosen wiring-connection to the ign.coil, as you've had your engine running ??
This is the only way I tried connecting the ignition coil so far. I must have missed the following comment you posted a few days ago:
However with your non-stock/Jap.coil, you could also try-out circuit-wiring it in a (more common) SERIES-circuit with the ign.points. _ This circuit-arrangement will rather create it's ign.spark due-to a SUDDEN collapsing flux-field (instead of the mere rapidly-expanding field). _ However, (even-though the resulted ign.spark is sufficient to run the engine), it's been my experience that various ign.coils merely create a somewhat weaker spark THAT-way (with pulsed-DC). _ So rather than having-to depend-on the collapsing-field of merely-just a single pulse of DC,, instead, you could rather store-up the other three (otherwise ignored & wasted) neg.DC-pulses and retain the combined energy of ALL-four neg.power-pulses (per Otto-cycle) stored into a capacitor, so as to 'filter' all those (originally separate) DC.pulses combined-together into rather 'straight-DC' and thus-then build-up a stronger & better-established flux-field before collapsing, to create a considerably stronger ign.spark.
Is that what you are referring to? If so, I will try out the SERIES scheme described above.
What type of capacitor should I be using (unless you are were suggesting re-wiring the existing points condenser(?))
Thanks
