Put engine back into ride on but wont start now

[Steve2018 3]

Put my briggs stratton 8hp engine back into my lawnflite 504 and now it wont start :-( don't seem to have spark,  it turns over ok but think i have connected a wire wrong somewhere.

 

Where should the engine kill wire go?  Is that the yellow one? 

 

Thanks

If you think that the yellow wire is the kill, check it out . With the ignition OFF you should have continuity to Earth . With it ON , it should be open circuit. When you say "wont start" do you mean totally dead or "cranks but wont run" ? 

The danger is that if you’ve got things wrong it’s possible that you may have put voltage through the ignition coil and cooked it, so the first thing to do is to isolate the engine. Disconnect all wires other than the heavy one from the solenoid to the starter motor and crank it over but be prepared to pull the plug lead off to stop it.  If it starts it at least shows that you have a runner and can relax and sort out the stopping!

I will dig out a wireing diagram but normally the kill wire will go to a terminal on the throttle plate and will have a loop terminal under a nut.

The 8 hp lump may have a single charging wire with a “ tubular” connector or a dual circuit  alternator with two wires and a double pin connector that can only be fitted one way round.

Yes, the yellow is shown as the kill wire. As well as going to the kill terminal on the ignition switch It is also connected to a couple of safety switches which will also prevent the engine from firing unless in the safe position.

Thanks sorted it out,  i think the wiring going from the governor to the ignition area wasnt making proper contact,  re done that and fired up now
