CB125T to total loss?

[k14]

Ok, I'm trying to convert the CB to total loss and I am a little bit stumped on one little aspect. I have removed the stator etc and had assumed that there would just be a single 12v output from this to the CDI's. However there are 2 wires! A blue and a white (if that makes it any clearer).

So I am wondering which one does what? I could quite easily refit everything, fire the bike up and use my trusty multimeter to determine the voltages but that requires energy etc and I'm lazy. The wiring diagram in my haynes manual depicts some sort of voltage divider with the wires coming off at different places.

At a guess the CDI's may work on 5v and there is a 12v signal through to the coils? Or I could be completly wrong and it may not be possible to conver to total loss?

Any thoughts appreciated.

OK I dont know about the Honda cdi but in general...

CDIs usually have source 2 coils one for high speed and one for low they just generate the high voltage needed by the cdi maybe 300v ? then the cdi dumps the energy into the coil when it wants a spark.

The other version and what you probably want is a 12v cdi the input is 12v and there is an inverter to make the 300 or so volts for the cdi output stage. This is the kind u use on a total loss system.

Depends on what you have as to whether you can convert it or not. I think Dangermouse had a cdi from a japanese 4 cylinder on his cb, but then you want to go fast i suppose

Take the easy way out and PM or ring Diesel Pig

I think the one on the Dangermouse CB was off a a GS450

If you want to run the ignition off a charged up battery you must determine if its runs off the battery in the first place.

I have a chinese engine in my moped and the igmition runs off AC power not DC 12volts.
It has a CDI which limits the revs to the makers specs
I wanted to run the ignition off the battery so I obtained a lumenation electronic ignition module without the infared trigger hoping to use the trigger that came with the bike engine but it was not compatable

I have been told there is something different about honda twins ignition set up and CDIs are hard to find
good luck
