Hi all you scootergurus…!
I have had a ´67 50N vespa standing in my garage for years
Now i want to use it, and therefore I have bought a primaveramotor on ebay in very nice condition
It is now fitted, but i cannot get any sparks from the plug (have checked by holding the plug to the cylinderhead…)
when I remove the ignition coil, plug and cord, and build a „teststand“ on my workbench, I can get a decent spark by touching the feedpole on the coil with my 6V battery charger…-so I guess that all those parts are ok…
The statorplate and the points seems very fine, almost like new.
One of my concerns are the fact that there are coming 5 wires from the primavera stator plate, and not only 3 as on the old 50cc motor:
(no brakelight and flashers on the scooter)
red = ignition kill switch
green = 6V lightening
Black = ground
(thats how I figure it)
From the primavera stator plate:
Red = from condensor and points = to kill switch
Black = ground
Blue = 6V (as I see it for brakelight)
Green = 6V lightening…???
Yellow = 6V (as i see it for flashers)
If I connect red-red, black-black and green-green, i can connect at testlight between the red feedwire to the ignition coil and ground, and get it to light up, but if i connect a continuity tester the same way and turn the flywheel by hand ther is constant contnuity all way round
if i disconnect the green-green wires, I can get hear the points open/close with the continuitytester, and cannot get the testlight to light up
(sorry I am used to work on cars, but the way i have figured it out the coil should get 6V-ground-6V-ground-6V-ground-… and so on from the stator plate)
should I connect all the 6V wires: the blue, yellow and green (parallel) to the green wire from the wireingloom on the scooter to get more 6V amps ?
I try to use this wireing diagram for reference:
any input would be greatly appreciated
