Noticed this on the
ignitor I I web page
"You cannot use solid core (typically copper) spark plug wires with this product. Solid core wires do not suppress electro magnetic interference (EMI) which will interfere with electronics in this product. A suppression style or spiral wound spark plug wires must be used."
http://www.pertronix.com/prod/ig/ignitor2/default.aspx
Yes same is true for Ignitor I modules
ADDITIONAL INFO: (Unless a radio suppression coil to distributor wire is used on Zipper as stated in literature.)
Here is a post from 2014 about a problem I had several years prior to 2014.

Default Re: FS ignitions hard starting
I have seen the slow starter problem with Electronic ignition 4 or 5 times.
1. Turn off key and crank ... if cranks faster then replace the coil to distributor wire with a carbon RESISTOR wire.
2. Try again. If still slow cranking then replace distributor body and cap with modern cap and carbon wires to the plugs. Leave carbon coil wire in place.
The electronic ignition module is picking up a random triggers from the high voltage or the starter brushes ... which causes erratic triggering of the module. The ones I saw were firing randomly while starter was cranking.
Maybe the module is picking up triggers from the sparks from the starter brushes.
Carbon wires reduce the random triggering while starter is cranking...
I do not know why this happens only on some engines ... maybe some starters are making more sparks.

I do not remember the exact year.
Engine cranked normally until ignition switch was turned on ... Then cranking speed slowed to "almost a crawl".
Fully charged Optima batteries were used ... We replaced the first Optima with a new one... same problem. checked for 6 volt cables, added ground to starter bolt from frame etc.
We fixed it by removing solid wires and using RFI suppression wires.

Default Re: FS electronic ignition
In the literature for the Zipper it states that solid brass strips for plugs are included.
BUT it also says that the wire from coil to dist cap is a special radio suppression wire.
I wonder if Zipper has some kind of radio suppression circuit built into the dist body maybe?
Quote from description:
""Your Zipper comes with a high energy heavy duty coil,
a radio suppression coil wire, a set of 4 brass spark plug connectors, a dedicated ignition wire, and of course, complete installation instructions, a trouble-shooting guide, and a 30-month warranty.""
Here is URL:

According to this the wires to plugs used are solid brass and ONLY coil to dist wire is radio suppression.

Default Re: FS electronic ignition
On 3 or 4 occasions I have seen a problem using FS ignitions (the one with module installed in stock distributor) where if you crank engine the starter kicks back and engine cranks slowly.
If we turned off ignition key it cranked normally.
This problem in all occasions was fixed by replacing solid core wires with radio suppression wiring.
According to Zipper info maybe only the coil to dist wire needs to be Radio suppression wiring.
I will have to test to see if this is true with the slow cranking problem.
