spjrr Posted July 5, 2013 Share Posted July 5, 2013 Need to replace plug wires on my son's 1940 dodge d17. Have been told by many parts stores they don't carry solid core wires in 7mm and don't recommend them for cars on the street due to RFI interference and they have been outlawed in many states. Has anyone tried resistor wires on one of these old motors before. I run resistor wires on my 69 vette that has point ignition with no problems, but don't know how it would work on this older 6 volt system.

Guest Bob Call Posted July 5, 2013 Share Posted July 5, 2013 I don't know about being "outlawed" but you can buy solid core ignition cables (plug wires) from performance stores like Summit. Also internet search ignition cable and you can find several sites that sell bulk (by the foot) cable and accessories. Also, stores like O'Reilly and NAPA should be able to get solid core. Modern silicone core is probably superior to solid core for a stock vehicle like your Dodge. Solid core is usually for racing applications where RFI is not a problem and the ignition secondary voltage is two or three times that of a stock vehicle.

spjrr Posted July 5, 2013 Author Share Posted July 5, 2013 Thanks, but still interested to see if anyone has tried resistor type plug wires on old cars with a six volt system. Yes I can order them from out of state, but none here in 7mm. I can buy race wires in 8mm but they won't fit through the wire routing thing they have on the old dodge. I have found 7mm universal resistor type and they look close to the stock ones that are on the car now. Thanks,Mark Smith Link to comment Share on other sites More sharing options...
Guest Bob Call Posted July 6, 2013 Share Posted July 6, 2013 All secondary cables are the same on both 6 and 12 volt. The 12 volt system has a resistor that drops the primary voltage to the coil to 6 volts. No reason that the silicone core resistor wires won't work just fine on your Dodge.

Guest Posted July 6, 2013 Share Posted July 6, 2013 Too much bother to locate solid core wire. I have used the various types of resistor wires since 1965. Never had any problem. I sure made my transistor radio quieter though. Link to comment Share on other sites More sharing options...
Curti Posted July 6, 2013 Share Posted July 6, 2013 Coles Ignition sells precut wires for your car. Specify solid or resistor core. A great place to do business with.[TABLE=width: 601]<tbody>[TR][TD]Coles Ignition & Mfg.

Rusty_OToole Posted July 7, 2013 Share Posted July 7, 2013 Suggest you get the wires from Andy Bernbaum and the Ever-dry kit of spark plug galoshes too, if you want your car to start and run in all weathers.Parts - Electrical | Andy Bernbaum Auto Parts for Chrysler's cars from 30's to 70's Link to comment Share on other sites More sharing options...
Guest rednwhitenblue Posted September 25, 2013 Share Posted September 25, 2013 I also would try RJL AUTOMOTIVE FASTENERS & VINTAGE WIRING SUPPLIES. www.rjlautofasteners.comThey are a company the supplies the catalog industry with their wire sets..All their wire sets are show quality. They carry 7mm cotton covered spark plug wires in many colors 9mm wires and 12mm wire. They do all their own manufacturing in Upstate NY. They have been doing this since 1976 Link to comment Share on other sites More sharing options...

Curti Posted September 25, 2013 Share Posted September 25, 2013 Curt, I was told recently that her business is up For Sale.I am sorry to hear that. Hilde has been running that business on her own since Joe passed away. Good People! Link to comment Share on other sites More sharing options...
Guest rednwhitenblue Posted September 25, 2013 Share Posted September 25, 2013 John passed away in 2007. The blood line family (John Cole) tried to get the the business out of her house (basement shop) and failed. So the family became a competitor to bring back the products Cole's cannot manufacture anymore. Cole's has no manufacturing resource, so they lost a lot of wholesale / retail business.

Marty Roth Posted September 26, 2013 Share Posted September 26, 2013 This is a good company to deal with:http://www.rjlautofasteners.com/decent, honest people who supply many of the others we deal with,and I've known the family for years Link to comment Share on other sites More sharing options...
ply33 Posted September 26, 2013 Share Posted September 26, 2013 Bought a spool of 7mm solid core plug wire from one of the bigger antique auto wiring houses many years ago. Can't remember which one now but I think RI Wiring, Harnesses Unlimited and YnZ's all carry the stuff. At tune up time I cut the wire I need off the spool. I get the end pieces and rubber boots from my local auto supply store.If your '41 Dodge is like my '33 Plymouth, you will be looking for solid black laquered cloth to be authentic. The above vendors should have that as well as the fancier looking multicolored stuff. Link to comment Share on other sites More sharing options...
