Hi, Can anyone give me some advise on helping me with my non starting engine please, engine cranks over fine but i have no spark from coils, somebody has pointed me in a direction of the engine kill switch or wiring, now this is where i need advice, as what i can see from my wiring diagram, which is on a cd and i cannot make out colour of wires but looks like it could be a black and red wire comes from cdi module and this wire goes to the engine kill switch and then this is sent to earth as long as key is present in switch ???? am i right or wrong and would this cause no spark to plugs, engine run fine last time used approx 6 months ago.
