Engine was swapped out in my Skyteam ST90 to a Thumpstar 120cc E-start engine. Engine is swapped everything is in, bike starts on first kick but the headlight, brake light & horn is not working. I'm looking for a wiring diagram for the bike or anyone that can help me with this. I went back to the thread where Daddysmut did the swap in his skyteam and the wiring info he listed there, followed that but still nothing. What am I doing wrong? Could it be a blown fuse? Ground wire? Power invertor?

See last page (non e-start version)

Sorry to bump an old thread. After much frustration and trying to contemplate parting it out, getting it sold as a whole or investing more money into fixing it, I finally discovered that the Skyteam ST90 simply is not compatible w/an E-start engine. There's no DC output from the bike. Is there any type of assembly, converter, something I can get to put on the bike to get this rectified? The bike will not stay charged because of this.

The rectifier is mounted on the frame under the tank. (front-left)
Did you put a fuse in the fuse holder? (glass fuse, 12V 10A slow)

For the E-start version you need a different ( >= 2005) throttle-switch cluster. that one has a starter button on the spot where the kill switch is now.

Or you just put a starter switch somewhere on your handlebars or frame, run a wire from (ignitionswitch)orange to switch and another wire from switch to starter relay.
For an e-start engine you also need a starter relay with the thicker wires. green going directly from battery(-) to startermotor and red going from battery(+) to startrelay and from startrelay to startermotor.

I found out that 2 wires on the harness for the voltage regulator was bad. Bike seems to be working now and putting out DC, yes!!
