How much resistance should a spark plug cap have?
How much resistance should a spark plug cap have?
Simply attach or hold a meter probe on each end of the cable and read the total resistance on the meter. The Society of Automotive Engineers suggests the maximum resistance should be 12,000 ohms-per-foot.
Where does the cap go on a spark plug?
The caps and wire are integral. The caps plug directly to the plug. Do they only unscrew from the coil side then?
How do you remove a spark plug from a coil?
The coil end should be twisted onto the terminal in the coil which is like a screw (at least is should be or id imagine it would vibrate out). Unscrew the cap on the coil and then unthread the wire. This set up is nothing fancy, just basic plug wire twisted onto a stud like cut to fit wire kits.
What to look for in a spark plug?
Look for physical damage to the wires or boots, such as cuts and scorch marks. Use a flashlight or an area with good lighting to perform a visual inspection of the spark plug wires and the cap on top of them, called the boot.
Where do the spark plug wires go in a car?
Trace each of the spark plug wires from its connection on the engine block to its corresponding spark plug. It is important that each wire goes to a specific spark plug. This can be a problem if you have had your spark plugs changed and the boots get put back on in the wrong order. Cross coupling can create an energy drain, causing engine trouble.

How can I check the spark plug wires?
Inspecting the Spark Plug Wires with the Engine Off. Look for physical damage to the wires or boots, such as cuts and scorch marks. Use a flashlight or an area with good lighting to perform a visual inspection of the spark plug wires and the cap on top of them, called the boot.
What causes a spark plug wire to slip?
Wiggle the end of the wire, making sure that the clips are holding the top of the spark plug solidly. When undamaged, they create the pressure that keeps the wire and the plug connected solidly. Damaged clips may allow the wires to slip and not hold their proper position. Identify symptoms associated with a faulty spark plug wire.
What can I do about arcing on my spark plugs?
Fill a spray bottle with water and spray all along the wires. You will want to focus your spray near the boots that attach to the spark plugs to see if any arcing occurs there. If arcing is found at the boot near the spark plug, turn off the engine and inspect the boots further.
