The big difference in CDI modules is how they trigger. Most flywheel magneto systems use a small "pulser" coil outside the flywheel to trigger the spark. This is how the P200 works. These need a power wire, kill wire, trigger wire and an earth, called 3 connection plus earth.
The system the R185 uses is internally triggered, that is triggered by the coil inside the flywheel. Power, kill and earth, called 2 connection plus earth.
The red CDI module is not ducati, in fact it is not quite the same either. It is missing a connection the kill switch! Not a problem though, just short the power through a suitable resistor.
Tyler,
Are you snowed in or something? This is a looong thread!
I usually use Yenntai coils, but I'm looking at buying a locally imported chineese product so I can just go and get them off the shelf. I haven't been doing so many conversions latley.
