The coil for the #1/4 spark plugs is mounted on the left side of the bike, and has the solid orange (ground) wire and the red-with-white-tracer-stripe (hot) wire input leading to it.

The coil for the #2/3 spark plugs is mounted on the right side of the bike, and has the solid grey (ground) wire and the red-with-white-tracer-stripe (hot) wire input leading to it.

No Spark, No Power coming from CDI to coil

Check the wiring on the connector plugs make sure all the wires are the same color on both sides, red to red blue to blue and so on. I had the same problem After replacing a stator and just plugging it in,after two weeks a new cdi and coil i noticed there were two wires transposed.

I replaced plug wires: unfortunately i got mixed up : plug1, plug2, plug3 and plug 4 ; please show me where the wires must go to.

hi you dont say what model kawasaki you have im assuming you have a transverse four like a z1000 generally speaking as you sit on the bike the outer cylinders are 1 and 4 the inner cylinders are 2 and 3 ,now again im assuming you have two coils, each coil has two plug leads
coming out of them coil number one will serve cylinders 1 and 4 it doesnt matter which of these leads goes to either 1or 4 as bikes use a wasted spark system and will spark on the exhaust stroke as well, coil number 2 will serve cylinders 2 and 3 again it wont matter which plug lead goes to either 2or3 ok now for the tough part
you need to find the sparking point for no1 cylinder remove no1 spark plug probably the outer left cylinder as your sat on the bike and turn the engine over by putting the bike in gear (only do this with no plug leads connected as it could start unexpectedly in gear ) and push or bump the bike gently with the clutch out to bring the piston to the top of the bore a small torch would be handy for this to shine down the plug hole you then need to find a timing cover on the outside of the engine
you may need a service manual for this as there are many variations but usally there are two pick up modules one for each coil the timing marks correspond to each coil with cylinder 1 at the top of the bore the timing mark should be near number 1 pick up module now that you know which module number one is follow the wiring back to the coil ,each pick up wiring is a different colour like black and orange wires for one coil and black and green for another when you have found number one coil attach plug leads to it and fit them to cylinders 1 and 4 you then fit the remaining coil with plug leads to 2 and 3 cylinders refit the spark plug take the bike out of gear and go for a start good luck with this

Where would the coil be located in the engine bay of the car. I bought a new one but cant find where it goes. thnx

find all your spark plug wires, they all lead to the coil from the plug. or... you may have individual coils over each plug but that is very very unlikely for your 1993. ps... why do you need a new coil, their are a few more likely solutions ahead of the coil pack.

Hi i just got a 1988 gsx600f i put new plugs in it tuck it out for a ride and it was running good then i gave her a little gas to kinda see what it would do and it bogged so i idled it home and statred...

it seems odd that your coils would play up, usally the they just stop working. You talk of it bogging down? , i would suggest that to be a carby problem, especialy if the bike has sat around for a while. first try to just drain the carbys, as you can do this without removing them, should be a drain screw or plug on the bottom of the carby. Make sure your air filter is clean too!

Hi and welcome to FixYa,

For and MC22, seated on the bike, the left hand ignition coil fires cylinders 1 & 4 while right hand ignition coil powers 2 & 3 cylinders.

Good luck and thank you for asking FixYa.

Spark plug order

If you are sitting on the bike, cylinder 1 is on your left then 2,3,4....looking at the coils, the left coil- left lead goes to no1cylinder. right lead goes to cylinder4. Right coil- left lead to cylinder 2, right lead to cylinder 3.
Hope it helps you.

Coil replacement How?

I guess as you may know , it has indidvidual coil packs for each cylinder. The ones on the driverside, 4,5, and 6 are easy to change. just unscrew the bolt holding the coil pack down on the plug and pull it off and unplug the coil pack from the locking plug by squeezing near the back where the wire goes in the plug. The ones on the passenger side require removing the intake manifold to get to them. This is not as hard as it may seem but the wires and a bracket connected in the back of the manifold do need to be disconnected in order to free the manifold for access to the coil packs. Wasnt such a hard job but a bit of a challenge.
