Situation:
SUNL 110 Chinese quad: replaced complete wire harness, with stator, rectifier, cdi, coil, starter relay, new kill / start switch on left handle bar and new key switch....All wired up correctly... everything plugged up together.

start button will not crank engine, does absolutely nothing, BUT... it I jump the starter relay with screwdriver, it fires right up,.... AND.... bike will shut off with kill switch, and key switch...

Im stumped!!! My next thought is the brake switch on left handle bar may be junk... I plug in the rear light... set brake handle, turn key on, try to turn on lights... nothing happens... when I jump start relay, with brake set try the lights... nothing!

im missing something, but not sure what! Faulty Brake Switch on handle bar?
Keeping quad from starting properly?

Im not worried about having lights, just want to get bike starting properly with button / switches
any and all help greatly appreciated!!

Thanks!
