Spark Plug wires resistance.

["John Hervey" <john@xxxx>]

Group, I checked the resistance on 3 sets of spark plug wires this 
weekend and found a big difference. The resistance was measured with 
a B&K Multimeter in the $100.00 varity and was from end connector to 
end connector.

Set#1. AutoZone, Omnispark. 7mm. All wires were around 5 to 6 thousand
ohms, which is fine for normal driving and RFI suppression.
( Radio interference.)But a little high.

Set#2. Bosch, 7 mm. All wires were under 1000 ohms. Still offers RFI
protection but better to deliver more voltage to the plugs
for a hotter spark.

Set#3. Taylor 8MM Pro Wires,Wires I'm working on and all are
consistance at around 500 ohms of resistance or less. 
Less resistance without going to solid wire is best for
street use. Won't cause as much interference.

Moral of the story is, If your experiencing maybe a cylinder that the 
plugs don't look like they are burning good or there is a idle mis 
but seems to disappear after you get going, it may be the wires. A 
bad internal connection when crimped will increase the resistance. I 
have seen as high as 25,000 ohms on a wire and will almost kill the 
spark at idle on a plug. Take your wires off and clean them or 
replace them and check them for resiatance. Also, Carbon tracks will 
build up in the distributor cap, rotor and wires and conduct 
electricity and cause a firing short or a plug that the spark is weak.
Call or email me if you need or want more information.
