Ok, a little follow up on my coil modification.
The re-wind coil get a outer layer of electrical insulation tape.
And then a layer of textile reinforced tape, this is ok because this coil is only low tension by now (this textile tape could collect some moisture). I prefer big heat-shrink tubing, but couldn’t find any in my stuff.
Coil in place, some rubber-shoe sole repair glue keeps the wires steady in the coil ends.
The enameled copper wire needs thorough cleaning, easiest is to heat it with a cigarette lighter, and scrape off the burned enamel.
The left side wire is soldered together with the orange wire, and connected to the condenser/points.
The orange wire is wired to the outside coil +.
The other end is cleaned, and grounded, this is often soldered to the coil core, in this case connected to a ground screw.
