My 1984 kawasaki ninja wont start? I put the key in the ignition and the lights come on and there is electricity but the motor wont start?

Does it turn over when trying to start? If no then it could be the starter, switch, or battery. Sounds like the starter, especially if you tried another switch.

I would try charging the battery. Take it off and put it on a slow trickle charge overnight. Batteries usually only last 3-4 years if it is an acid battery.

sounds like you have a carb problem Jason,possibly probably your float level is set too low not allowing sufficient fuel to Venturi

Try jiggling the handle bars as you turn the key to relieve the pressure off the ignition lock. The kawasaki's have one position past the off "Lock" position that is called the "Acc" this will leave your brake light on. So the key switch goes "Acc", "Lock", "On". Make sure your key is in the Lock position and not the Accesory position

Hi and welcome to FixYa,

To my knowledge, there would only be 3 wires needed from the handlebars that affects the engine:

• engine RUN/OFF;
• clutch ENGAGED;
• engine START.

The first 2 would go to the interlock plus the neutral wire and the sidestand wire. The interlock then sends signals that starter motor can turn and that CDI can fire.

As to the ignition coil, 1 wire is IGN B+12 while the other would go to the CDI and should pulsate when cranking or engine running.

Good luck and thank you for using FixYa.

If you can't find another similar connection on the new motor, you might need to swap heads (if it's the same exact motor).
