How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

A good spark will be blue-white and will be plainly visible in daylight. If a good spark is present, the problem is probably not in the ignition system. Check the fuel system and/or stark timing. Weak sparks are orange or red and may be hard to see in daylight.
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
If there`s no spark or the spark is weak, check the resistance of the wire that connects the ignition coil to the distributor cap. Consult the wire resistance specifications in your repair manual. If resistance is within specifications, continue with the next steps; otherwise, replace the wire and test for spark again.
With a poor ground the starter ring return path may not allow adequate amps to return to allow a starter to reach the torque and speed to start. Normally, however, with a well tuned car and cranking, the engine will fire right up. Weakness, though, and it may not start.
Make sure the spark is strong and blue in color. If the spark is weak and dull orange, it`s likely that it`s not strong enough to ignite the engine`s air and fuel mixture. (Optional) if There Is No Spark, Connect a New or Known Working Plug Connect a good plug to the coil pack or spark plug wire and repeat the test.
Blisters on the insulator tip, melted electrodes, or white deposits are signs of a burned spark plug that is running too hot. Causes can include the engine overheating, incorrect spark plug heat range, a loose spark plug, incorrect ignition timing or too lean of an air/fuel mixture. The spark plug should be replaced.
A weak spark is the first sign that the ignition coil may be failing. During acceleration, the air and fuel that is forced into the cylinders extinguish whatever spark there is, which causes the car to stall.
If the ignition coil does not have spark, it`s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
If the house is not earthed, people could get electrocuted. Without an earth connection, the safety switches will not work and an electrical fault could cause a house or appliances to become `live` as the current flows to earth.
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. A blue or white spark is strong and has enough voltage to fight across the spark plug gap even under pressure within the cylinder.
One of the key factors that makes a spark plug work well, or not, is the size of the gap between the electrodes. If the gap is too small, the spark will likely be too weak and cause the engine to run poorly or with poor efficiency.
