Hey guys. I am on the last leg of my xs build. I put a hhb complete cdi system and a key from tcbros. Bike runs well and shuts off as usual (through the key). I am not running a battery (kickstart and capacitor instead) I am trying to figure out the headlight/tail light and can’t seem to find power through the key like the wiring diagrams show. I tested the headlight on the battery in my pickup so I know that it’s not burnt out, but I am scratching my head on this. Any suggestions or things I can try?

What wiring diagram did you use?
A pic of the diagram would be helpful.
A basic diagram just substitute your capacitor where diagram shows Battery.

The important concept is that this system has TWO completely separate parts. One ONLY makes ignition, the other provides all the other electrical needs for the bike. The ignition is turned on/off by use of a ground lead, (cut off wiring) here. Ground that lead and no spark, The grounding is usually done by a relay powered by the "lighting coil side" of the PMA

Put your Cap where diagram shows battery.

Are you using a relay?
The Vape system is near identical
