Well... this is the story:
The CDI was defective the black/white wire never "kill" the engine and the next day it didn't work at all....the HPI guys sent me a new CDI module on warranty, installed it and everything seems to work O.K., black/white wire working, engine turning on well, etc. but....the next day, it doesn't work AGAIN!!!!!.....after checking ALL the wirings, I found the CDI isn' providing energy to the coil AGAIN!!!!!, all I can see is that I made the orange wire (+ coil) longer, about one meter, this to reach the coil's original location (As from factory)...do you think guys this "new" resistnace could be burning the CDI?
