Yes grumps...that diagram. No its correct what confused me was the primary and secondry coil section...but if you look at the primary trans coil inside the magister is in two winds,one inner one outer....so its all good....when I looked at it I firstly thought it was the magneto coil...all good:)

Blumblys coil was meant to have been tested and operational by my understanding.

The green wire is the feed from the primary magneto coil to the rectifier and loops back into the switch then into the primary of the trans coil....So it can never work!

Ok its fairly simple in the flesh I just need the parts.

my aim is to make a module like the magi but smaller and mount it under the fly plate unseen. The coil wire will leave there and pass through a dummy hole in the real magister and the wires will hook up as normal but dead ended under the fly wheel.

essentialy it will look as if nothing has changed.

just need the parts and the other two values for the rectifier and trans coil...hopefully my electronics mate will be able to work it out via the capacitor value. Or compared with a std victa coils rating....

Ill just be patient and see what gadge can come up with

cheers guys...

Puts it aside and plays with my new aquisition ....Villiers Villager mmmmmmm
