You posted your problem way out on the fringe of chinese quad territory
, so it hasn't been noticed by the chinese quad regulars. A better place would have been the chinese quad section where there is much more traffic.
No matter. We can continue from here.
First, I'm impressed with your frame mods. My chinese 150cc quad has been solid as far as frame issues.
Are you still having problems? Got a voltmeter? I think we can solve this problem easy even tough I don't have a wiring diagram. The plan will be to:
1) Find out what plugs are disconnected.
2) Get the quad to crank the starter.
3) Get the quad to start.
4) Check the charging system to see if the quad battery is getting charged.
5) Fix any ancillary items such as head lights etc.
A) What plugs are you having problems with? Can you post pics? What are the wire colors? How many pins?
B) Have you checked the main fuse?
C) Is your ignition switch (follow the wires) plugged into the main main wiring harness (sometimes you have to remove body plastic to see this)?
Go ahead and reply here, but for future problems (for you and for the general public with chinese quads watching this) post in the chinese section for best results. If you get uncomfortable posting to such a large (and sometimes hostile) audience you can private message me. I prefer public discourse because many others will benefit from the dialog, but it is ultimately up to you. I will respond either way.
