This is such a repeat over and over question about 12v rectified / regulated lighting so leds can move reliably used that I decided to post this picture seeing I'm doing thisntona hpi mini.
As I've previously said hpi listened to various desired for floated ac so they made it easier to do it. Not as easy as they should on this version by not as hard as older generations. This one the cdi ground ( black wire and the back side of the three lighting coils end together so separate then with a side cutter and then silver solder the wire to a new second wire and bring out under the stator and include inntheboutbound wiring harness. Yes!!! I was somewhat delirious the day I put t on the mutant hobbit ad forgot this cdi wasn't floated hence now I'll end up probably needing to pull stator etc to get it all out and secure. I'll put a bit of shrink wrap over the soldered connection
