brad Posted December 28, 2022 Report Share Posted December 28, 2022 Silicone jacketing. Regular Studes had neoprene wires. Also, they seemed to leave off the shielding covers on Avanti equipped R3s Link to comment Share on other sites More sharing options...

Dwight FitzSimons Posted December 28, 2022 Report Share Posted December 28, 2022 They were a light orange color, similar to the University of Tennessee school color. --Dwight Link to comment Share on other sites More sharing options...
Nelson Posted December 28, 2022 Author Report Share Posted December 28, 2022 Without looking at old Paxton sales literature probably no one will get the question totally right. Yes they were 7mm diameter orange/flesh color silicone casing with BRAIDED STAINLESS STEEL CORE. Link to comment Share on other sites More sharing options...

Yes they were 7mm diameter orange/flesh color silicone casing with BRAIDED STAINLESS STEEL CORE. I assume that the stainless steel conductor was used for SS's higher resistivity (vs. copper). That would reduce current like resistor wires do, although less. I also remember that they were rather "leaky", meaning a lightning show when running the engine on a dark night. You're right on the color, a very light orange/flesh. This was on the R3 engine I bought new in the crate about 1967 (B86). --Dwight Link to comment Share on other sites More sharing options...
