Wiring Gurus

I have changed my switchgear. Old GPz750A2 for a newer ZX6R. All working as it should apart from the start button. It will start the bike but when I let the button go it dies. On the attached document the old is on the left. Both have a Red and Yellow/red wire which I just swapped over to the correct place and the only two left are both Black. On my wire harness they are both black at both sides of the block connector. The ZX is Black/Red going into a Black/Red and a Red. Could these two be the problem being in the wrong way round?

The wiring looks to be correct as you describe but are you sure the switches are the same type i.e. it could be that on the GPz when you pushed the stop button it made the circuit and on the zxr when you push it breaks the circuit. Either for a stop is feasable.

Can you disconnect one of the blacks and see if the bike continues to run or use a multimeter to check the switches with the wiring disconnected?

No you've got the starter miswired too. The on/off switch is merely a yes/no connection so swapping the wires will do nothing. They are the wrong wires!

Screwd.

Easy way to check if gs is right. Start it with the switch off!

Cant look more at it today as its started raining. The GPz had a cobo kill/start switch where the ZX6 is two switches. The ZX6 kill switch seems to be doing its job as the bike will not start when off so this only leave's me two wires, The Black and Black/Red.

Logically if those are the correct wires, either it will start with them connected or disconnected and whichever way around they are. If you've tried that you've got the wrong wires. It is perfectly feasible for the starter to start using say, one of the kill switch wires so don't give up yet.

Ill not give up it’s just a pain as starter will run and so will bike but both stops as soon and I let the button go. I was half expecting a third wire to be in there where two would make the starter connection and the third to keep the bike running. I’ll take apart both switchgears tomorrow and follow the wires from each button to the harness. Surly I can’t go wrong that way.

How about i have my live for the kill switch and starter the wrong way round?

You need to go further back along both wiring diagrams.

On the original one you've got a Red to the Kill switch and a Yellow from it, and two Blacks through the Start button

On the new one there's a common Red to both switches - the Kill switch becomes Brown/Black and the Starter button becomes Black/Red.

I have the two wire diagrams and to be honest they could have written them in Swahili. Looks like one from each goes to the starter relay in the fuse box but cant find the other yet. Trouble is the wire diagram is separate from the main one in the GPz book and they dont mention the colours. Looks like i am going to just sit and try trial and error until i get it right.

At a guess, I'd reckon you've got the starter switch and the kill switch swapped over. On stock switch gear, if you hold the starter button in and flick the kill switch to on, the bike would fire over and then die when you flip the kill switch to off....

Looking at the full diagrams again i am thinking its the two blacks. The red from the start button goes back as black and then on as red to the coils. The other goes to the starter circuit relay. Think that will be my first switch over in the morning.

If you put a meter on the feed side of the coil,I think you'll find it's only live while the starter button is pressed.The feed should go through the kill switch,you've got it through the start switch.

That was my thinking last night. If i am correct the Red to the stop switch is the live in and when it turns to black going to the coil this is where i kill the power going to the coil using the switch. With me having the blacks mixed up then i have the start button doing this job. Ill pop out later to try if the rain stays away

Got it. I had my polarity the wrong way round (twat) Looking at the manual and the item i was popping the spades back in the block as a mirror image.

Oops.

Thanks for your impute guys
