I "think" I might have bad sparkplug wires, they look damn near new (borrowed from a supposedly running engine), BWC brand blue copper-silicon 8mm suppression wires.

anyway to test these?

Somewhere in Cyberland the information exists to determine if they are faulty. It has to do with OHMs resistance and I can't remember the figure for a "good" cable.

They are checked with a VOM, DVM, etc.,

They could have an internal break too!

Measure the resistance, you will see a couple kiloohms per wire if they are the resistive type. I think it's around 1 kohm per foot but don't quote me. If you see over 3-5kohms something is probably wrong. If they are not resistive wires you will see very close to 0 ohms.

The probability of all 4 wires being bad is probably pretty low Mike.

Try this:

Sounds like the wires are copper, you should measure approximately 1K ohm due to the resistor in the sparkplug connector. You should also measure the resistance of the rotor. It has a built in resistor in the tip. Resistance can be good!, and is required, for those thinking of removing!

The wires can still leak spark to ground if there is a void in the insulation.

Other areas for spark problems: if using points the, points and condenser, also the internal breaker plate ground braid. The ground braid is also required, and is very important if using the Pertronix or Compufire point replacements.

Points and coils can easily fail if ignition is left on with a stalled engine.

So, when you walk into the FLAPS, you see several spark plug wires with associated claims to superiority. What is the bottom line? Is there properties other than resistance to look for? What about silicon vs other?
Kit, how is your FI system comming?
