No resistance specs or chart is needed to figure out the correct spark plug wire resistance on any set of spark plug wires. A spark plug wire test with a multi meter can determine if the conductors are good.

This is such a great video. I had a perfect LT (primary circuit) state but no HT output to the plugs. My problem was a faulty lead from the coil to the distributor. Plug leads are very difficult to check on your own, as it's hard to correctly ground plugs and see spark strength when you're turning an engine over. This solves the problem with respect to the leads - as you say consistency is the key - making sure the resistance takes account of lead length. Clearly explained and demonstrated. Now - come and take a ride on UK roads in a Triumph TR6...

don't stop keep your nice work we can use multimeter to diagnose almost everything around us cars, home devices, electronics, solar system, batteries , phones, HAVC, etc and actually everybody must have a pocket multimeter in the car its always helpful even if it low price multimeter (but just for cars simple diagnose not for serious electricity work in this case it must be high quality multimeter for safety and always use it with extreme caution). i like your video and after i read your replies on comments i subscribed and by the way not everyone understanding fast it's different from person to person so my opinion is your video wasn't long.

The check engine light came on with a P0303 code for cylinder three misfire. I am going to try to help him figure it out. My code reader, which is the BlueDriver, said the most common fixes were plugs or the cam sensor. I will see. Runs great at idle so I don't think it is a vacuum leak. Thanks, Tom

still confused. so, the service manual or all data has spec numbers based on wire length? that test is rather inconclusive. your service manual says that your reading should not be greater than 25k ohms. how helpful.
@Know-How-Now4 жыл бұрын
If you want exact numbers you may want to try to get them from the wire manufacturer. The test lets you figure out approximately how much resistance for a length, then with a little math you can get rough idea if all of your wires are in the ball park of what they should read. If the insulation is breaking down, this test won't help.

is there any sequence to plug it depending upon its resistance?

I'm not real clear on your question, Saad. I will try to answer. The longer the wire, the higher the resistance reading. You'll need to test all of the wires to get make an educated guess on whether or not the wires are good.
@saadali69264 жыл бұрын
Know How Now I meant that the longer wire usually have more resistance and the shorter has less resistance comparatively, so is there any specific sequence for plugging the wires? like the longer wire must be plugged into the first spark plug and the other end into its rightful place and not plug the longer wire into the third spark plug...?
@Know-How-Now4 жыл бұрын
You have to connect the wires between the distributor and the cylinders according to the firing order for your engine. The longest wire will go to the cylinder farthermost away from the distributor. The 2nd longest to the next farthermost cylinder and so on.

Continuity is around 0 to just a few ohms.... that's what you would read on a few hundred feet of #14 copper wire. Spark plug cables are supposed to read much higher resistance per foot than a copper conductor. www.championautoparts.com/Technical/Tech-Tips/Defective-Spark-Plug-Wires.html

I made the video because it's difficult/impossible to get the specs (as you have discovered) for your particular set of wires. By comparing them, you can get a rough estimate of how much resistance you should read on each cable to find out if it is broken/damaged inside of the insulation and make an educated guess to replace them. The insulation on the cables breaks down over time and that can fail too. I have no way of knowing the specs for each one of your cables, especially something so small a .4 ohm. Depending on the quality of a multimeter you could have .4 ohm difference from one meter to the next. Likely, your question needs to be answered by the engineering department of the manufacturer. Sorry, I am not one to give you an answer to a question that I don't have the ability/information to answer.

Got me wondering why @iwana would think a longer cable would mean less resistance. Probably they rationalized a scenario in which 2 cables of different quality or gauge had similar resistance. In which case the longer cable would get less resistance per inch/meter and hence heat up less. Then it might seem that a less heated cable got less resistance.
