Hi All, I am a new member and my name is Dave, I am a newbie to scoots.
i have never owned a scoot before and really wanted an old Lambretta (must be mid life crisis) however I got a call from a man I know saying he has a couple of old Vespas for sale so I went round to look at them but never in a million years thought I would buy one.
one was a 1980 150cc and the other was 1963 125cc, as soon as I saw the nice chrome on the 63 I just had to have it despite being a non runner - it just looked so great I forgot about LAmbrettas in a heartbeat and parted with £1300 - non runner but 100% complete and great bodywork as had been imported from Indonesia some years ago.
looks like its 5 years old, not 55.
i have spent the last few weeks reading up the ignition side of things as I don't have a spark and have about a million questions and am really sorry to be asking advice, there is lots of info out there but there is so much it's hard to pin down the needle in a haystack with limited knowledge.
the diagram for wiring a vnb4t seems to suggest the ht lead is soldered directly onto the ignition coil and the goes onto the spark plug, however my three coil / five wire stator may have been replaced at some point as I don't seem to have a place to connect it to on the internal coil. Is it obvious where it should go ?
I also have no continuity through the ht leads cap (which I find crazy), but do have resistance of 4ohms, I have tried a few caps I have and they are all the same.
when I got the scoot it has a 6v external ignition coil and a 4 picofarad capacitor next to it, what is the capacitor for ?
also, replacement internal ignition coils on forums and shops seem to have more windings than mine- I seem to have just 15 and others seem to have 25 - is this an issue ?
When I kick start I get 6v generated by the internal coil onto the red wire, the red wire is joined in the terminal box to the external ignition coil and the capacitor and goes to the engine kill switch - but no spark.
i have replaced the ignition coil so it can't be this, the points look good but I'm no expert - what should the surface look like?
is there a way to test the condenser as a lot of sites recommend changing this.
finally I am confused by the fact I have continuity to Earth on most of the staters cables except one, is this right ?
the engine has fantastic compression and so looking forward to getting on the road, can anyone help me find my missing spark ?
