What should the resistance be on my spark plug wires. I’m testing them to ascertain if they are what’s preventing my engine from running, but am finding conflicting answers online as to wether my resistance is for too low or far too high. I got a somewhat consistent reading of .3 ohms on a couple of them, and was wondering approximately what reading I SHOULD get for good wires. Thanks for the help
If you look at a Buick Chassis manual, the spec is 2000 ohms/ft, not to exceed 20,000 ohms on any one wire. Those are typical for the day, carbon core resistance wires. If your engine isn't running, the wires are not the cause.
I am getting very weak spark to most plugs according to my spark tester, I don’t see why bad wires couldn’t be the problem
If the wires are in the same ballpark, it is more likely something else. They would not all go bad at once. It is a high voltage low amperage circuit so the wire resistance is not so important. Does your car have a distributor that uses points?
It's possible, but not likely. What kind of wires are they? Are they carbon core? Or are they the better spiral core? Are you running points or something else? If you are running points, do the tests in this thread, http://v8buick.com/index.php?thread...ystem-function-tests-and-modification.248990/
What type of spark tester are you using? If you are using a HEI tester on a points system, may show as a weak spark. At my first dealer job as a mechanic, I spent all day trying to get a Pontiac T1000 to start. I used a spark tester for a standard ignition and thought that I had good spark. When the mechanic that worked next to me came over and used his HEI tester, I had no spark.
