How to test the spark plugs on a Harley Davidson?
To test the spark plug wires: 1 Set your multimeter to read ohms. 2 Place your multimeter probes at each end of the spark plug wire. 3 Measure the spark plug wires resistance level. A normal reading can be between 1 and 20,000 ohms. The reading “OL” stands for open lead and indicates the wire is bad.
What to do if there is no spark at the end of the spark plug?
If no spark is present at the end of the spark plug wire, the air/fuel mixture cannot ignite. Remove your spark plug wires from the spark plugs. Insert a spark tester into the wire and attach the tester to ground. Remove the fuel pump fuse. Refer to the article Fuse Box Information for fuse locations.
Why are my spark plugs not working on my motorcycle?
Spark plugs may not create a spark when the ceramic case is cracked, the electrode tip is broken, or the electrode is worn. If the engine has been running poorly for some time, the plugs may be covered in soot or fuel. To check, clean, and replace the spark plugs, refer to the article How to Replace Spark Plugs and Plug Wires.
What are the steps in installing a wire harness?
Installation requires four (4) easy steps: 1. Connect to the fuse block 2. Route the wires 3. Cut off the excess wire 4. Terminate the wires 5 2.0 ABOUT THESE INSTRUCTIONS The contents of these instructions are divided into major Sections, as follows:
What was the color of the spark plugs?
Wire Script Color: original script ink type and color (white, black or yellow). Wire Braiding: original machine-applied metal braiding (only 1965-74 Corvette big block with radio).
When did spark plugs start using Date coded wires?
For the restorer, we manufacture date coded spark plug wires. But what are “date coded” wires? In January 1961, spark plug wire manufacturers began to print date codes on their wires for their own internal identification (quality control) purposes. Note: 1961 G.M., Chrysler and AMC vehicles built prior to January 1961 did not use date coded wires.
When do Lectric spark plug wire sets come out?
Lectric Limited’s spark plug wire sets are either dated the first (1-Q) or third (3-Q) quarter of each year, starting with 1961. Second and fourth quarter dating is not available at this time, nor should it be necessary due to the wide spread of 1 month to 12 months previously mentioned.
What are the symptoms of bad spark plug wires?
This is necessary due to the aging of the spark plug wires from exposure to extreme temperatures (hot and cold), engine chemicals (oil, grease, coolant, etc.) and electrical stresses. Common signs of failing spark plug wires include a decrease in power, acceleration, and fuel efficiency.
