Hi Guys,
I am replacing the stock coils and wires soon with the dyna setup and bought the solid core wires instead of the resistors. I think I read somewhere that you actually get a hotter spark with the resistor wires My brain is still in the hot rod days when resistor wires were the first thing to go.
I am also putting in the Irridium plugs which I believe are resistor also. The stock plug connectors seem to also have a resistor as part of it.

I always thought that the resistance was just for radio static elimination and had nothing to do with coil output.

Any light on the subject would be greatly appreciated as I usually deal in mechanical things, as in 8-10-12-16 and 20lb sledgehammers

I dont have a good answer for you. Tomorrow, I too am going to install new coils - Nemesis - and the Maxair 7mm high temp radio suppression wires using the stock caps with iridium plugs. I read this thread and am considering replacing the resistor in the cap w/ #6 copper wire I have laying around.

I use solid core wires without problem.

The resistor in the circuit results in a slightly weaker but longer spark. The resistor would have no detrimental effect until the plug becomes a bit fouled.

The resistor leads will give you a much fatter angry spark for the want of better words ,its like forcing water through a smaller nozzel,it comes out harder and faster,radio suppression is a side benefit,back to work for me John

Spark plug wires are a conductor, that's it. it's only going to send the electrical current that's needed to jump the gap.

Electrical devices, including SPARK PLUGS, use only the electrical energy necessary to perform the function for which such devices are designed. IGNITION WIRES are nothing other than conductors, and whereas an ignition wire's inefficient or failing conductor or insulating jacket (particularly a jacket inside grounded metal shielding) can reduce the flow of electricity to the spark plug, an ignition wire that allegedly generates an "increase" in spark energy will have no effect on the spark jumping across the spark plug gap, as the energy consumed at the spark plug gap won't be any more than what is needed to jump the gap (e.g. a 25 watt light bulb won't use any more energy or produce any more light if it's screwed into a socket wired to supply current to a 100,000 watt light bulb).

Finished the install. Took about 1.5 hours start to finish. I am anal when it comes to spot tie... more stuff to tie up under the tank. Have not taken it for a ride yet but when I twist the throttle, it goes NOW! Got a Honey-do list to go through before play time. I left the cap resistors in for now for comparison sake. One change at a time before I move to something else. Gotta make sure all is well first. Nemesis coils are a bit larger and had to finesse them into position.

Thanks for the description Erbman, Doc and Aussie John.

Thanks guys, I will use the solid core wires that I have and the stock caps which look better than the ones that come on the wires.
I wonder if the solid wires cause cell phone interference ? cause if they do I will throw a couple more coils on and rig'em up to a whip antenna off the sissy bar

I would use the spiral wound wires and get the best of both worlds. RFI suppression and less loss on the wire. You have to have some resistance on the discharge side of the coil or you will not develop the voltage necessary to get your hot fire spark. The gap in the spark plug is a large resistance and serves that purpose well.

Musta hooked the coils up wrong, better read the book before I cause real trouble

If you run the solid core wires with dyna coils you have to reuse the resistor caps from old stock plug wires.

They simply unscrew off old wirs and you can then reinstall on new solid core wires whic is what stock setup/plugs witres were too.

But if you got supression core wires then you dont have to run the stock resistor spark plug caps.

Without resistor wires or resistor spark plug caps on solid plug wires the interfearance could cause issues with the ECM in some cases .
