With very basic tools. Most of these systems required no maintenance except replacing the spark plugs at intervals from 60, 000 to over 100, 000 miles. The points require periodic adjustments in order to keep the engine running at peek efficiency. If the tester stays OFF while cranking, there are 3 possibilities: Points shorted (stuck closed). Every time the points open, the flow of current is interrupted through the coil, thereby collapsing the magnetic field and releasing a high voltage surge through the secondary coil windings. A voltmeter is helpful (I prefer the older. Voltage can even be stepped up before sending it to the coil, so the coil can create a much hotter spark, on the order of 50, 000 volts instead of 20, 000 volts that is common with the mechanical systems. BTW, I have found that an emery board for finger nails makes a good points file. 12 volts to coil but no spark wire. What if my ignition coil has power but no spark? How can I fix no spark? Still no spark at coil wire. I have a simple dwell meter but the only time I've adjusted dwell was on distributors with that small window and an allen head screw to twist while the engine is running. The low voltage primary circuit operates at battery voltage (12 to 14. Alternatively, it could be a bad ignition module.
I don't remember the correct gap for this, but to my eye it looks too tight, but that wouldn't explain the lack of flow between the points. In a normal AC transformer, the ∆T (delta T) nulls out so only the ratio and applied voltage determine the secondary voltage, but the ∆T is different in the charge time and discharge time of a coil of a Kittering ignition system. Ok thanks for all your help, going to order the conversion kit monday, hope this fixes it. Why Does My Motorcycle Have No Spark? 11 Things to Check –. That is sure to cause spark problems. Failure of the ignition control module will result in a weak spark and an inability to start the vehicle.
In the case of the automobile, the negative battery terminal is connected by a heavy cable directly to the body and the engine block of the vehicle. Some "Solder Wick" a braided bare copper wire designed to collect heated excess solder, aiding in joint preperation. This is done during a routine major tune up. If the readings are far from what I indicated, I suspect the coil is shorted internally and needs to be replaced. It is difficult to diagnose a failed stator, but a stator generally deteriorates over time. 7) Expected Resistance: Many manufacturers indicate variations considered in the acceptable range. No Spark From Distributor To Plugs: Test & Causes. In older vehicle models, the distributor is an integral part of the ignition system. Both Vacuum and Centrifugal advance systems worked together to extract the maximum efficiency from the engine. Vibrations can damage ignition coil windings and insulation causing shorts or breaks in the secondary windings. The alternator output "Bullet Connectors" are usually behind the engine sprocket cover and will need inspecting and cleaning too. Let's take a look at each section and explore it in more detail. Points have a life expectancy of about 10, 000 miles at which time they have to be replaced. The 550's, 650's & 750's may be backwards to the Z1's, Kz900's, Kz1000's & Kz1100's.
Checking for spark is pretty easy to do. One of the telltale signs of a faulty ignition coil is the engine dying suddenly after running for several minutes. 12 volts to coil but no sparknotes. You can replace the secondary coil wire on an engine that uses one with an equal length of vacuum hose and the engine will start and run. Open the choke, peer down into the openin with a flashlight, operate the throttle linkage manually, and see if it sprays gas. The (-) side of the coil will have varying voltage depending on whether the points are open (0V) or closed (12V).
With the ignition OFF, disconnect the spark plug wire from the coil, and remove the two smaller primary wires from the coil. Second, it must control the timing of that the spark so it occurs at the exact right time and send it to the correct cylinder. If replacement pickup coils are not available, your next choice would be to order a Dyna "S" electronic ignition system from It replaces the IC igniter with a smaller module located where the mechanical ignition advancer was mounted. Apply a small amount of flux to the joint to be repaired & then a very small duration of heated soldering iron tip & solder. 1986 Martinique 351 windsor, points ignition. No spark to ignition coil. Excessive heat and vibration can cause the insulating material to break down and create internal coil failure.
But the ratio is only 100:1 so that would only generate 1200 volts in the secondary. FIX: Replace the damage section of wire or the faulty connector. Misfiring can be caused by loss of spark; imbalanced air/fuel mixture; or loss of compression. The ignition coil is the component that converts the 12 volt signal into the high 20, 000+ volt charge. If you're looking for a reliable mechanic to perform auto repairs, look no further than RepairSmith. 1960s vintage technology - how to troubleshoot a no spark condition - Maintenance/Repairs. The electronic ignition pickup coil sits inside the distributor and triggers the ignition system to produce a spark. Secondary Resistance Check. The ignition system's sole reason for being is to service the spark plug. And if the bike is in gear, the clutch needs to be pulled in. Replace the coil if the above test shows the coil open. Injectors can release fuel once the ECM receives signals from the crank position sensor.
I'm grateful for the good help. The DTC numbers show specific circumstances where the collected data does not meet acceptable values. On some vehicles, points are adjusted with the engine off and the distributor cap removed. When the crank sensor begins acting up, it can't supply the ECM with the correct information. This may seem obvious, but double check that the key is in the ON position in the ignition switch and that your kill switch is flipped to RUN.
If points, they may be stuck open or closed, if electronic ignition, check the pick up coils(usually behind a CD sized engine cover). Vacuum advance uses a vacuum diaphragm connected to a link that can move the plate that the points are mounted on. While you've busy at the battery, check the fuses. The most important tool, apart from a multi-meter, is the one between your ears.
Pull out the lower HT lead from the coil pack that you plan to remove. If it still doesn't start, the problem has to be fuel, air or compression. So when the key is turned to the spring-loaded start position, full battery voltage is used. Unplug the electrical connectors of the coil pack and use a wrench to remove the coil pack from the engine.
