Is there any way to test spark plug wires with a volumeter. I have herd that there is a certain resistance they sould have in ohms. Thanks for all the help.

Yes, Take your mutimeter, and put it on Ohms (upside down U with feet) then touch the leads to each end of the wire.

It should give you a reading.


Also you can check continuity just to make sure its working right.

i dont know how many ohms they should have, but i would hope they have next to none.

I dont see why you would want resistance on your spark plug wires....

The reading should not exceed 16kohms per 3.28ft(1meter):muhaha:

audio master's correct. I couldn't believe that when I tested my 85k mile old NGKs that all were within spec. I think my longest lead had 6kohms of resistance, most were 4.5-5. Replaced 'em anyways due to mileage/age.

Typical measurements are approximately 1.000 ohms per inch of wire
example ...10 inch wire 10.000 ohms
i believe that reads 1,000 ohms per inch...& 10,000 ohms. it even says in the instructions to set the meter to the 40 kohm range meaning you're reading kilo (or 1000) ohms.
