I am in the process of converting my VBB2T from 6 volts to 12 volts electronic ignition, and being a bit of an electrical ignoramus who is colour blind, you can imagine that things are not going smoothly! However, I do have a friend who is a bit of an electrical guru, but he is struggling to help as well; so here is my problem which I do hope someone can help me with.
Bit long winded, so please bear with me!
I have fitted a 12v electronic Bajaj stator plate. Wire colours from stator are: Red, Purple/violet, Grey, Green and Black. Using kickstart, I am getting power from the red and violet (both plugged into cdi), and green. Attaching a wire to the bottom terminal of the CDI, I still get power from the unattached end, but when I attach to coil connecting terminal, there is no power coming through to the HT pin!
If I put my electrical tester pen onto the metal part of the coil, my pen lights! If I connect my cdi to engine case thereby earthing it, no power from cdi to coil!
We have tested both cdi and coil and readings are within tolerances!
I have attached a couple of pics which hopefully may help. I am only trying to get the engine started at this time. Am I doing something stupidly incorrect, missing something obvious?
All help gratefully received. Tia.
