Title: What, no real spark plug wire? Post by: W3RSW on January 02, 2013, 12:14:57 PM Went to NAPA today to pick up five to ten ft. Of non-resistance plug wire, silicon impreg. Insulation, etc. needed to rearrange a HV supply under the op. desk. Wire I bought before was 3/8ths thick and all business.
"Uh, we don't have any ". Really? "yeah, all our stuff is in sets, coil to plugs and resistance wire.". ..."uh you might get some at our warehouse.." Second salesman was almost huffy about it. Well how does a guy wire up his model A or whatever? "uh, dunno." No "sorry 'bout that," or anything close. Like the Queen, I'm in the wrong generation again.

This i s not local stock for you, but the first place that comes to mind is: http://www.mgs4u.com/RF-Microwave/high-voltage-wire.htm Surprising that Napa does not have it. Perhaps there is a local Speed Shop or similar. 73 GL, Vic Title: Re: What, no real spark plug wire? Post by: KA0HCP on January 02, 2013, 12:44:02 PM http://brillman.com/store/paper-catalog

Title: Re: What, no real spark plug wire? Post by: W1ATR on January 02, 2013, 10:17:17 PM How about trying a local sign shop. They should have some GTO-14 laying around they could throw you. It's not uber flexible like old school plug wire, but it's good stuff. 14ga stranded/15,000v

Here is the real deal, very pretty 7, 8, & 9 mm cloth covered, modern insulated inside: http://www.magnetoparts.com/wire.htm 73DG Title: Re: What, no real spark plug wire? Post by: Gito on January 03, 2013, 01:58:26 AM Hy
why not using a CO AX cable as the high voltage cable with a solid dielectrik.not a foam type. Gito Title: Re: What, no real spark plug wire? Post by: NR5P on January 03, 2013, 09:10:35 AM Also places that sell boats and parts carry solid copper plug wire
Title: Re: What, no real spark plug wire? Post by: W3RSW on January 03, 2013, 09:34:59 AM Lots of good places to get it. Thanks guys.
I just couldn't believe an auto store didn't have a roll of just plain ol' HV plug wire. Very same place I got it before... Granted, some years ago. Reason I used it before was the easy trip to the store, oil and gas resistant, suitable dark manly bown color, steel wire. ...yeah, right. Regarding coax, yes, believe it or not the HV connector on my twin 8875 amp is a SO-238. Planned that way since only running 2kv. Been FB, hokay, since 1982. In physics and electron. Lab we used large coax for just about all the HV runs a/c what was thought of at the time as add'l safety plus continuous shielding. Title: Re: What, no real spark plug wire? Post by: Gito on January 03, 2013, 07:52:11 PM Hy I believed They did not Sell non resistance spark plug wire,is because the RFI that is caused by the Spark plug.with this cables caused Interference to the Radio and audio system in the Car maybe the computer system in now days Car So maybe no "one" will buy it and so the shops did not sell them.

Yes, you are correct. RFI has been the reason for several years. Also modern electronic ignitions are designed to compensate for the resistance wire transit time and rise time of the igniton spark, etc. You may recall that once upon a time cars like British Motor Corporation's MG had a spark gap before the mechanical rotary distributor to retard and aid in the timing of firing. This is why I teased the NAPA auto store sales people for not having non-resistance wire for the Ford Model "A", which you may know is a 1929 year automobile. ;D |
