No Spark- help needed please..

[Gyesdad]

My GPz1100A1 has decided to shut itself down...
I took it for its MOT, it behaved perfectly there and back so I got it home and left it for a couple of days. I was off out for a ride on it, went to start it and there was nothing.
It will turn the engine on the starter with a screwdriver across the starter soleniod posts, but if I press the starter button is doesn't turn over.
I've WD40'd the sidestand switch, fiddled with the killswitch but nothing.
When I turn the key I can hear a click from the fuseboard, and all the warning lights come on as you'd expect- apart from the battery warning light (because it has no probe for the electrolyte level) which used to flash with the DFI light before this problem. Not sure if this is relevant but I'll menton it anyway.
There is no spark at the plugs.

It has been converted to cards, so there's no DFI set up to interfere with things.
Any ideas? Help would be greatly appreciated.

Thanks in advance.

Sounds like you have a bad or broken connection on the low tension side,have you a circuit diagram? its going to be a process of elimination here,you were right to look at the side stand and kill switches,would short them out and try that first also check earths,also check fuses are all intact with a multimeter and make sure fuse contacts are clean if thsis fails see if you can locate a circuit diagram post it on here and i am sure someone will help...Cheers Paul j

Handle bar kill switch/starter button probably shorting out

Thanks fellas, I'll give your suggestions a good looking at. It will be Monday now as I'm working over the weekend.
I've noticed that there are connectors for the ignition circuit in the headlamp shell.
Are they worth looking over too?
Thanks for your help.

check the yellow wire with the red trace at the starter solenoid this should become live when you press the starter button. if it is live you should be looking to replace the solenoid. if you don't have battery voltage when you press the starter button to this wire your problem is more likely to be the switch. or problems with the brown wire into the switch as this is the switched live feed on every kawasaki

Stuck this problem the other day...
Nothing when I pressed starter button.
Would turn starter motor when shorted solenoid across two main terminals.
Battery good.
Suspect all mentioned above... Z1Bman would have nailed it, except i'm not sure if checking the yellow with red trace would have shown anything odd directly at the solenoid.
Ended up being the primary windings in the starter solenoid. I think this is rare!

Sorry Gyesdad, You heard a "click"... usually means the solenoid is working!

Gentlemen,
I finally got to have a look at this tonight- I've been working away quite a lot recently.
Turns out whoever rebuilt it routed the wiring from the right hand switchgear incorrectly around the fork leg and every time the bike was on full right lock it gradually pulled one of the block connectors apart until it seperated completely causing the problem.
I'd like to say thank you for all your suggestions and advice, I'm just glad it was something simple..

That's a good result.

and even better everyone else was wrong

Don't Paul,
I spent hours with lighting probs on my old H***a CB900F and the Wife kept saying "have you checked the bulb?"....of course as an electronic engineer I know best and it is far more complicated than that....and some time later it is of course the fecking bulb........

Electrics. Don't you just hate them! (Not to mention women who every so often happen to be right)

I made the fatal error of telling her....15 yrs later and it still gets brought up...
