What causes a no spark condition open loop?
If after unplugging the 4-plug connector there is no spark or the spark still looks weak, this tells you that the problem is in the major ignition components like the stator, coils, cdi, spark plugs, spark plug wires, possibly a short in the wiring harness, a bad trigger coil or on EFI models your Injector Coils are bad (they measure 19-20ohms).
What to do when your engine has no spark?
Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. Finally, Have someone crank the engine and watch for spark. Remove one of the coils from the spark plug. Use an extra spark plug. A spark plug tester. Or even a screwdriver in the end of the coil.
How to diagnose no spark or weak spark?
Diagnosing no spark, weak spark or intermittent spark issues First is separating the issue between switches or the primary ignition components like the stator, cdi, coils, trigger coil or possibly plugs or plug wires or plug caps.
Why is there no spark in my ignition?
An ignition module requires some type of external input in order to activate. If your vehicle stalls unexpectedly during operation and will not start again, it is likely because of loose or corroded electrical connections in the ignition module. In this case, check the switch, clean oxidized terminals, and replace broken wires if necessary.

Is the spark plug part of the ignition system?
Something else is going on, and there is a very strong possibility it is with the ignition. The ignition system is considered to be passive. The spark plug only takes from the ignition coil what it needs to create an arc across the plug’s electrodes. It must be recognized that ignition demand is determined by the following:
What are the issues with a no spark motor?
Other issues related to a no spark/Weak Spark/Wet Plugs issue: Wrong flywheel on it. Sled was only running on one cylinder. Low side coil on his stator read 360 ohms and it should have measured 450 ohms. The low side coil was bad. It kept fouling plugs left and right. The guy before ran ethanol, and never told the current owner.
How do you check no spark Arctic Cat?
First put the spark plugs in the spark plug boots and lay them on the cylinder head bolt away from the cylinder plug hole so they are grounded. If you pull the sled over and the spark plug is over the spark plug hole and it sparks it will ignite. Pull the recoil rope and check the spark at the plug.
Can a spark plug make a motor run poorly?
Spark plugs with the gap set too small on them can make the motor run poorly. If you have no spark and your trigger tests ok, your stator tests ok and you have tried a new set of coils then we’re possibly looking at a bad CDI box. There is no real good way to test the CDI other than swapping the box out with a known good CDI box.
When does a car engine have no spark?
If a connecter becomes 100% disconnected or if a wire gets cut then the switchwill no longer turn off the engine but the engine will still start and run. Diagnosing no spark, weak spark or intermittent spark issues
What to do when your car has no spark?
When taking on a no spark condition one needs to be patient and have an open mind. Becoming fixated on specific components is a good way to not find the true problem. It’s far more likely that there is a problem with a wire, connector, ground, or switch than an actual ignition system component.
How can I tell if my Kawasaki ZRX 1100 is running?
Try pulling off the suppressor caps one at a time when the bike is on idle (or pull the cap with the engine off then try to start) – a change in note or engine cutting out will tell you which cylinders are okay.

Why is my Kawasaki ZRX running so slow?
If its only done 20k the shimms shoulda been done at 15k . Poss slow running jet or jets . Is the filter clean . the air filter looks a bit manky in all honesty. could this be causing me mega probs?
