A replacement set of pickup coils might be obtained from a dealer who serviced the police Kawasaki's. This should read between 0. Okay, so we've established that your motorcycle is getting 12 volts to where it is needed to start the sparking process. But if Im not getting any spark out of the coil then the problem must be from there back right? LEARN MORESEE PRICING & SCHEDULING. I am guessing there is corrosion on some terminals causing resistance thats just a guess. 4.3 no spark voltage at coil drops from 12.6 to 2 volts or less while cranking | Page 2. Look for electrical arcs and listen for a snapping noise that may indicate a high-voltage electrical leak. Posted: March-25-2007 at 10:09am. Ideally the condenser would prevent this, and it does greatly reduce it, but typically there is a small spark. A rusty or dirty distributor cap. Double check that there is power at Terminal #15 while cranking the engine with the key. A damp sponge to keep the soldering iron tip clean. If the spark is weak or orange, it is probably your coil not generating enough voltage.
You should get a nice fat spark jumping off the wire…. Does the rotor spin when you crank the motor? Spark plug wires have to endure the heat of a running engine as well as the extreme changes in the weather. Modern ignition systems "detect" the need for a spark through a hall-effect switch or crankshaft position sensor instead of interrupting the circuit via breaker points. 12 volts to coil but no spark plug. 1: Ignition and kill switch switched on; safety switches off. The most common cause for a misfire is a problem related to the ignition system. Schedule Engine is misfiring Inspection. Anyway, its a straight six, starter button on the floor, with ignition/ key switch on dash. Voltage transformation produced by the interruption coincides to each spark generated. There might be intermittent engine failure if the ignition control module in your automobile is malfunctioning. The heat range of a spark plug dictates whether it will be hot enough to burn off any residue that collects on the tip, but not so hot that it will cause pre-ignition in the engine.
The turn signal light sockets will benefit from a spritz from the contact cleaner along with the tail light/brake light socket. It's important to remember that many times when a coil fails, it becomes weak. Next, you'll want to measure the resistance of the secondary coil, and this is the real business-end of the spark-producer.
OK, we have 12V on the + side of the coil, 6v on the -ve side of the coil (measured from the terminal to the engine block with a multimeter) with the key in the "run" position, There is no spark at the king lead. The coil primary winding contains 100 to 150 turns of heavy copper wire. Is your bike very old and in bad shape, or did you recently drop it? The ignition coil is the component that converts the 12 volt signal into the high 20, 000+ volt charge. HELP - No Spark from the coil. When cranking, both sides get significantly dimmer, about equally so. Hi Just got my GS455 all back together.
This wire must be insulated so that the voltage does not jump from loop to loop, shorting it out. As current flows through the coil a strong magnetic field is built up. It's been so long since I worked on this kind of stuff that I'm just rusty on it. Some switches, like my side-stand safety switch, have three terminals. Ok to answer your question, yes there is normally a small spark.
So here is My question, how do I get spark from coil? The ignition switch may or may be not sealed to allow spraying the internal contacts. So I got my #1 cylinder to TDC and about 35 degrees on timing mark. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil. This may be difficult in daylight, so try to shield the light or do it at night. I know how to set the gap with a feeler gage, but that's so frustrating. Power to coil but no spark | Retro Rides. Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. Don't start replacing parts before confirming the cause. If you don't have a helper, you can do it this way: Pull the hi-tension lead out of the distributor cap and hold near ground. Chris Weis is a freelance writer with hands-on experience in accident investigation, emergency vehicle operation and maintenance. The car's other components may be OK; the issue is only the switch that turns the engine on and off. The coils on early Corvettes are black cylindrical devices; starting in 1975 the coil per se as a discrete cylindrical device was abandoned when GM made the switch to HEI breakerless ignition systems.
G. The fluxed joint should clean up, allowing for a better connection. These electrical wonders come in many configurations and heat ranges to work properly in a given engine. Unplug the wires that go into the switch and use your multi-meter to test resistance. That is sure to cause spark problems. The low voltage primary circuit operates at battery voltage (12 to 14.
The crankshaft position sensor tracks where the crankshaft is and how fast it's spinning. So I started from the begining, check if I have power at the coil and that checked out ok but the problem is that I get no power using a meter, from the positive side of the coil to the negative side of the coil. Please help, its 80 degrees here and the family is dieing to get on the water. Images (Click to enlarge). If this happened, it could not create the primary magnetic field that is required. 12 volts to coil but no spark videos. I am at a loss as to what to do. Check the ballast resistor/wire coming off the distributor. 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. Checking with website has determined that the Pick up(pulsing) coils are available. That keeps the high voltage out of the computer that is triggering the spark. I do have the test light and can follow your good explanation.
This system was always computer controlled and contained no moving parts, so reliability was greatly improved. That is where the spark occurs. Stalling: a failing ignition module can occasionally prevent the engine from getting spark, causing it to stall. 12 volts to coil but no spark parts. In some cases, to keep the engine running efficiently, a minor tune up would be performed at 5, 000 mile increments to adjust the points and reset the timing. Part 3 of 4: Test the spark plug wires. The basic principle of the electrical spark ignition system has not changed for over 75 years. If your bike has the older style glass tubed fuses, I suggest replacing them as vibration can cause internal failure. If the spark plug is misfiring, you may want to replace it. It must provide sufficient voltage to jump the gap at the tip of the spark plug and do it at the exact right time, reliably on the order of thousands of times per minute for each spark plug in the engine.
There should only be two gray wires going to the - side of the coil. While setting the initial, or base timing is important, for an engine to run properly, the timing needs to change depending on the speed of the engine and the load that it is under. The condenser is a simple capacitor that can store a small amount of current. Check the distributor cap inside for signs of cracks or carbon arc tracks. This is called the "firing order" and is part of the engine design. A separate spark plug wire connects each spark plug to the outside terminals of the distributor. You should get some kind of spark, although if you turn slowly the spark may be weak.
