Check my plug wire test results.

Try as i might i cant seem to find answers on google. So, If you wouldnt mind checking my test results, that would be great! Here goes,

All tested on the 2000 ohms Hope that works out,

Coil 412
#1 1361
#2 1458
#3 1183
#4 1499
#5 1045
#6 1293
#7 981
#8 979


So what do you think?

The longer the wire the more reisistance there will be. Without knowing the brand of wire you're running and the reccomended ohm's of resistance per foot of wire it's hard to say. Those numbers all look to be in the same ballpark considering length.

#1 is close to #2
#3 is close to #4 etc. etc...

If this is a stock replacement set I'd say you're good to go. If you had a bad wire it would have noticibly higher resistance than all the others or show open.

Been a long time since school but I remember a general "rule of thumb" for measuring ignition wire resistance. Something like 1000 ohms per foot. Someone correct me if I'm wrong.

In the real world of auto repair I've never had to ohm test a set of wires. They've always been either plain as day bad (burned on a header or arcing all over) or replaced via maintenance interval.

Is there a certain problem you are looking for? Suspecting a bad wire? Spray them down with water while the engine is running, better yet, do it while it's dark and watch the sparks fly. Water will help the spark "leak" out of any bad wires and the engine should start skipping if the wires are bad.

Yea i have one plug that seems to be not firing and trying to figure out why.

pull them off one by one at the spark plug end with your bare hand while its running.....

you'll figure out if it's firing or not....


seriously..... most ignition systems will bridge a gap of 2 inches if the wires are any kind of good.....

if the plug is stone cold dead with raw gas on it ,, a little resistance in a wire isn't your problem...

it's shorting to ground or there's something going on inside the rotor cap.... pull the cap and look for carbon tracks or something burnt up on the rotor contacts...

I always though the 1K ohms per foot was the rule, but on my 98 Chevy, They all checked in the 1.3K to 1.8K. The new wires checked at .2K to .4 K. After changing them out, it made a world of difference.

I might just toss a new set on any way at $21.99.
