Rich running conditions: If your engine is running too rich, the spark plug will be black and sooty. White, no color on spark plug: Too lean. Lean running conditions: If your engine is running too lean, the spark plug will be white. Good running conditions: If everything is good, the spark plug should have a tan/light brown color. Rich running conditions: If your engine is running too rich, the spark plug will be black and sooty. Dark brown or Black Spark Plug: Too rich; Black, oily Spark Plug: Oil fouled (see valves or piston rings.) White, no color on spark plug: Too lean. Good running conditions: If everything is good, the spark plug should have a tan/light brown color. rainer-daus.de › spark-color-to-determine-ingition-coil-performa. That's because the compression ratio is higher than that on an air cooled. On an automobile ignition system the spark should be bright blue. A blue or white spark is. The strength of the spark is revealed in the color. A red or yellow spark is weak and probably will not spark in the cylinder. That's because the compression ratio is higher than that on an air cooled  . Dec 23, On an automobile ignition system the spark should be bright blue. But on an automotive engine with a higher compresssion ratio and under transient conditions the yellow spark can get quenched thereby causing a misfire. This is called quenching the spark. A low compression engine running at a steady state with a constant fuel supply won’t quench even a spark plug with a yellow spark. A low compression engine running at a steady state with a constant fuel supply won't quench even a spark plug with a yellow spark. But on an automotive engine with a higher compresssion ratio and under transient conditions the yellow spark can get quenched thereby causing a misfire. This is called quenching the spark. Spark color is often changed by resistor cables as well, you. 5 ohm (thats one half ohm) and the coil resistor should be about the same or less. . Aug 12, The strength of the spark is revealed in the color. A red or yellow spark is weak and probably will not spark in the cylinder. Furthermore, indicating the plug is in the correct heat range; and, has been operating in a “healthy” engine. Normal Spark Plug Color. Combustion deposits are slight and not heavy enough; to cause any detrimental effect on engine performance. Note: The brown to greyish tan color and minimal amount of electrode erosion. If you have a weak spark, you may be dealing with a. The spark on the tester should be a bluish-white color; an orange or red color indicates a weak spark. When the mixture is lean, the flame cannot expand across the cylinder bore since it requires both fuel and oxygen to accomplish this. The engine will be weak, the unburned fuel will foul the spark plug, and the exhaust will pop. If the mixture is excessively lean, the engine will misfire since the fuel molecules in the intake air are too far apart. While the color in air can be observed against a dark background, it also will not tell if the coil, or the points are pitted, etc, and results in charges of. If the spark is weak it will be orange in color, so now check the other wires the same way, if the tests are all orange, then now it's time to. Dec 19, The spark plug only takes from the ignition coil what it needs to create The engine will be weak, the unburned fuel will foul the spark  . It resembles a spark plug but has a sunken center electrode that simulates a load on the coil. Check a no-start. The spark is arcing in atmospheric pressure. The proper method to check for spark is with a spark tester. Holding the plug wire and seeing if a spark jumps to ground is inconclusive. Leave the plug tester connected too. Sorry for the confusion. As suggested, lay the plug on top of the engine, crank it over and look for spark on the plug itself. Most likely your plug tester isn't going to change colors with spark strength as it appears it's a bulb type and the spark is not jumping through air to a ground like the spark plug.

The other real longshot is that the grounding strap between the engine/trans, body, and negative battery terminal is corroded/worn/damaged. May 20, at am # Bryan LaTraverse. If the spark is still weak after replacing the whole ignition system, then the normal size wiring or connector to the coil may be corroded or damaged somehow. I measured stator volts, 37 AC, then I tested resistance. Charging coil gives ohms, trigger ohms. Carb is checked and cleaned, mixture is set turn. I am out of ideas. Fuel gets into engine as I can smell it and spark plug is wet. Problem is I get spark but it doesn't look solid and thick. Yes, it ran ok on high rev and didn't like idle. A red or yellow spark is weak. from rainer-daus.de The strength of the spark is revealed in the color. Edited May 14, by bcgold Tractorhead lack of performance is replaced by madness Supporter 7, The test light is neon energy from the high intensity ignition spark excites the gas to emit light which indicated the system is live. What colour is the spark at the spark plug gap, should be lighting blue, orange indicates bad condenser. Then pull the air duct off at the throttle body elbow, open the throttle, and spray the ether in it. E.) Coil weak or intermittent - you should see 3/8" fat blue spark with a good coil 3.) Spark at spark plug, but no start. Next, get a can of starting fluid (ether) from your local auto parts store: costs a $ or so.
