Dennis Savarese) ________________________________ Message 1 _____________________________________ Time: 06:11:54 AM PST US From: Cpayne Subject: Yak-List: Spark Plug Wire Just a reminder that only Racing Wire is recommended for the "automotive" plug conversion. Passenger car wire has a resistive core intended to suppress RF and IMF emissions. This wire is designed for high voltage systems. racing wire uses a tightly wrapped shield of stainless steel wire around a copper core to provide suppression. This is the type of wire to use with our magneto systems. It offers lower electrical resistance but is more expensive. Either the Taylor wire that Dennis offers or Magnecore is good. Diameters over 6.5mm must have the outer sheath tapered to fit into the distributor cap. Regarding the spark plugs, what we are using are types designed for motorcycles and recreational equipment. I use the NGK brand because of the choices in heat ranges, and cheap price. I use the 1/2" reach but has anyone experimented th more expensive fine wire types that have a broad heat rage??

Dennis Savarese" Subject: Re: Yak-List: Spark Plug Wire No tapering of the wires required anymore Craig as I now provide an appropriate size drill bit in the kit to enable the installer to drill out the magneto cap holes. This allows the 8 mm wires to fit neatly and snugly into the holes and more importantly, prevents the end of the wire from "rolling" or "moving" in the hole when the small piercing screw is screwed down into the end of the 8 mm wire. This assures proper contact with the center core. I also provide NGK plugs in the kit now because they are easier for the customer to acquire locally at an auto parts store than the Champion plugs were.

Want to use P.S. engineering PMA 4000 as a primary PTT type intercom and to switch between radios. The PMA 4000 only provides a single lead to each com thru which a ground is applied to transmit. Anyone know if the Russian PTT swith closes a circuit to the Russian Com or if it just applies a ground the com? any info on this application would be appreciated.
