c.o.p's help
 

just like to say hi everyone! i'm new to forum read it alot but just signed up. i have a 2002 f-150 4x4 with a 5.4 just started to get a missfire. my ? is i see from other forums you are buying you're cop's on ebay but when i go there they have about 5 different kind uneek,rally,alanis,aip and parts highway. which one is better? also wondering how many are made with copper wire and which ones are made cheap with aluminum wire? none really say what they are made of so how do you know? thanks for the help!

Don't know anything about materials, but many on here have had good luck with Global and Uneek on ebay.

Link ~ "COILS (COP-10pk)"

Not sure on the windings. All my Global Coils are good, so their in one piece. I have two sets of Motorcraft Coils that went bad, yea, I cracked one in both sets open, their copper. I believe ALL coils in the COP systems are copper. I've never heard of or seen Aluminum coil windings. Where have you?

Bought a set of 8 from Global and have been running them for awhile now no problems....:thumbsup:

don't know which one's are made with aluminum windings just that parts highway say's made in usa with cooper wire and beware of ignition coils made with aluminum? http://cgi.ebay.com/8-NEW-USA-MADE-C.../130471107053?

Huh, okay, I see what mean. I'm curious as well. I've never seen them advertised this way. I have half a set of new Globals,-still in the box. I may cut one open out of curiosity, - if enough people are just as. No ambition at the moment lol.

Interesting. Could just be a sales pitch? I mean he is advertising them as "part brand:Motorcraft". Or maybe there's some truth to it. Jbrew, you said you already cut a motorcraft cop open? Ive already installed my globals or I would cut one open. But I do have a set of motorcrafts. Im curious now. Curious to see a uneek and global torn down.

i just order a set. think i'm going to try rewinding one of the old one's looks like a winding on a stator and i rewind them all the time. just have to find out a ohm reading on a new one. should be able to rewind one for about $1.50 in wire and ten min's. of time.

Ok,,who want to tear um down?
I got a set of uneek's here I'm gonna through away. :smoke:

Phil

why are you throwing them away? are they bad if so how long did they last?

I think I'm making to much power for them.
I know everyone on here has great luck with them so it must be my truck.
I bought 10, put 8 on and one was bad from the beginning.(Good thing I got the 10 pack) Replaced the bad one and 3 more went bad in less then a 1000 miles.:eek:
So I ended up putting the Motorcrafts back on and replacing the bad one of them when I finally found it.

Phil

Crack ones skull open Phil, - see what it looks like :D

When I disected the Motorcraft, I gave it squeeze in the vise until the top blew off. Make sure that thing is pointed away from you and don't be eye ballin it :eek: - , just listen, you'll hear it, - like CRACK, BOOM!

That's ^^^ the procedure. ;)

Just moved not long ago and have no vise or a bench to put it on.
Plus I'm lazy! :lol:

jbrew is it just a post inside or is there two a primary and secondary? look like it could be rewound?

Geeze, I can't remember what it was wound around. When I broke it open, it was a known bad one for sure and I was looking for burnt windings. There was no evidence what so ever, - that's as far as I went with it. I didn't remove the entire housing, just the top and about 1/2 way down.

Also, the top came off fairly easy. The sides of the housing alligatored and cracked, but was a PITA to remove. It was glued pretty tight something else inside or the outer windings themselves. That's about all I can tell yuh.
