Well i have been working on a 86 DT 150 and have not been able to find a CDI for it so I bought a 2001 cdi it looked kind of the same but it has different wire colors so I am trying to figure out which wire is for the IC power charge and battery charging coils , so i thought that if can look at the diagram i can make this CDI work , it'll be greatly appreciated this way i dont have to buy a hall new manual just for the diagram thank for any help any
