Number 4 on the wiring diagram is the handlebar switches, of which only 1 wire input ( the one attached to the coil ) is relevant as the kill switch. This system has no ignition module like a traditional cdi set up which is why it’s so different and awkward to fathom. I think I’ll send it to motoplat for testing.

Managed to get the flywheel off despite not having the correct puller. These are what’s inside. The bottom of the windings had a spring loaded plate which may act as a magnetic points system?

These wires to my “regulator? “ look correct but I have no rectifier which perhaps should be where the wires are twisted.

Unfortunately my wiring has already been messed with but wired from stator are correct and are linked as per the diagram. Blue to the coil is a larger connector so must be correct. With a spur going to my kill switch as per numbers 9-5.

There is also this old thread on here titled 93 beta zero ignition systems. Let us all know how you get on with it.

I have one with no spark too. I have found this so far but can’t find any readings for resistance etc.
