ZX9R NO SPARK
Hi
Guys
I have aZX9R C1 does any one know any good wiring guys apart from the oracle steve keenan as he is fully booked
Using a Sierra Ignition
Orginal bike ignition
Vicky Green Loom
all the wiring is in and connected
we have no spark / and no power to fuel pump
Does anybody know what the 4 wires out of the bike ignition are connected to as somthing tells me where missing somthing here.
plus me and charlie are getting splinters from scratching our head so any help would be apprieciated thanks Chris

Sounds as if you haven't got the 100Ohm resistor in the gray wire that takes a positive feed to the ECU.
Unfortunately, my scribbled on haynes manual is at home and I can't remember what colours the others are.
Someone should be along soon, if they're not, I'll post the details when I leave work

Have you got a 100ohm resistor connected to the ecu? if not it wont spark. i'll have to dig out the wiring diagram to tell you which wire it
needs to be on. Somewhere i have a wiring diagram that i got from ST which i can copy for you if need be. Live to fuel pump is from ignition
switch.

Could I have a copy of the ST diagram if you can find it?
Cheers

No Spark
So i still need a resistor even though i am using the bike ignition as an anti theft becasue if you put a peter across it gives 9.5v instead of 12v
if you have a copy of the stuart taylor diagram that would be good thanks Chris
PS if any billy wizzes out there would like to have a look for me the car is maltby rotherham.
Thanks Chris

if your using the bikes ignition switch (key)
then im sure you dont need one
but if your putting it to a sierra ignition then you will need it !
i get this alot with mine (b4)
when ive played with the wiring,
i have to disconect the battery and reconnect it and it ok then!
have you had it running at some point ?

From your original post, I assumed you were using the sierra ignition switch with the bike ignition system - in that case you would need the
resistor.
If you are using the complete bike ignition system and the original switch, AFAIK you don't need the resistor because, as you said, it gives the
required voltage drop in the switch.
I have the bike ignition system wired to the sierra switch and it definitely needed the resistor. I found this out as I managed to forget it despite
having read it many times before

or even better forget that engine and give it to me !
got a nice sierra engine to swap with you

Spooky... I had this problem too!
I experimented by changing the resistor to one that had a higher wattage and it stopped doing it. Don't know why it worked?

I've an 'E' model wiring diagram in my archive. It is similar to the 'C' model so it might be helpful
Oi, diagram is here!

That's the one
Saves me going home early (not!)
Resistor goes between white and grey

NO SPARK
Hi
Guys
yes i am using the sierra ignition which is wired to the vicky green loom
i then have the bike ignition which has three wires
Grey
White
Brown
i have grey to grey vg/bike loom
White / green Live on Vicky Green loom
Brown to Brown
Thanks Chris

Sounds about right.
White 12v feed from battery
Grey switched to ECU (I have this wired to posn I on the sierra switch)
Brown main ignition (wired to posn II on the sierra switch)
Then again, I have basically added the (very few) extra wires into a complete bike loom. I've no experience of the Vicki Green loom.

the 100ohm resistor goes into the grey wire to the ecu.

hi ,I have a very similar problem, ZX9R engine C1 ,I have got it turning on the starter,fuel pump is running ,but no spark,I have tried 2 different
100 ohm resistors wired into the ecu feed but still no spark,is the wattage of the resistor critical? help !

no it's just got to be 100 ohm , you can take a look at my website beneath the engine button, you will get some answers

Did you
Connect the 100ohm resistor between the grey and the white battery wire to give the correct power to the cdi ?
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Wadders,
could you do a copy of the diagramme to me or scan it and post here? there seems to be a lot of interest.

Hi thanks for those answers,I think I have made all the correct connections,fitted correct resistor in the right place ,but still no spark ! I am
beginning to wonder if the ECU is faulty, does anyone know who could test it,or if I could try my ECU in someones working car ?

send me your addy and i will post you a resistor to try
had to buy 200 of the babys so got a few spare
thats if you want to try one

thanks for the resistors Paul,I still have no spark. I suspect the ecu could be faulty, so if there is anyone within a few miles of me,with aZX9R C1
(or C2?) could I try my ecu on your car? then at least I will know if mine is broke before spending money on a replacement , thanks
