coil packs

Postby Honker91 » Mon Sep 09, 2013 11:01 am



Hi, everyone. I have a 85 aspencade. I lost the coil pack for the rear plugs, front plugs coil pack works fine. My question is? Is there a automotive coil pack I can use to replace both of them. I thought I read something awhile ago on a neon coil pack, but can't find anything on it now. Any help would greatly be appreciated.

I found, what you're looking for, under HOW TO ARTICLES. That's a very interesting conversion. 1997 Dodge neon coil pak

This article, is extensive, with pics. You'll have to, go to, the article. It shows, which wire, goes where. Look above this reply, "how to articles" Then go to search, extreme right top. Put 1997 dodge neon coil pak. I have found so many "FIX ITS" here. Goldwing Docs, is the place to look. Good Luck, Amigo.

Look up what you said to put in search and found nothing on 1200. 1100 are different wiring colors. But I did get the neon pack put in the stock location with factory mounts. Fairly easy.2-black/white12+, blue/yellow sender for back two cyclinders, yellow/blue sender front two cylinders. But I still have no fire to the back plugs, it has 12 volts going into coil, and im getting a fairly close reading on the meter when I checked both sides at new plug. Anyone have any ideas on what could be causing it? Accel pro copper core wires, ngk plugs, god what a difference the front plugs can throw and inch long spark. Back are dead. Help!

Well, is there a spark, at all 4 posts, on the coil? Does all 4 wires, throw a big spark? Are the wires, from the coil, to the bikes wires, reversed? The blk/yel (center) wires, are the power, to the coil. ARE THE CYLINDERS DEAD? Is the coil, pak, good? I sure hope, you find the answers, I'm interested, in this project. Good luck Honker91 (I think, 1100 and 1200s, have the SAME wiring, maybe different color codes.)

There are 3 parts to the ignition system
Ignition coil
Ignition module
Pulse coil.
Which one is bad.
You just eliminated the coil,now look at the 4 wire plug to the left of the battery.Its the pulse coils.
Continuity check the pulse coils and inspect for corrosion.
There are posts on how to test the pulse coils with a cheap meter.

Heres the test on new plug. Blue/yellow stripe starts at .124v jumps up .244v. Yellow/blue stripe starts at .048v jumps .260v. Checked the pickup pack, 4 wires coming from it, all tested good.but I did notice the cdi was really hot. All wires coming from cdi are hardwired, no plugs, same as rectifier, and stator.i switched the leads on new plug to make sure it wasnt the coil. Rear plugs fired no front fire. So its somthing else. What are the voltages suppost to be at wires on plugs that hook to the coil packs?

When you switched the coil wires,did the good spark stay on the same coil or did it move with the wire.?

It moved with the wire to the other coil pack. So I have one dead sender wire. But I had a voltage reading and jump and down. So im not sure what the reading was suppost to be. Starting point was very different. High point about the same.

Here's more info....Determine which color wire is on the dead coil...Cut it loose at the ignition module and disconnect it at the coil...temporarily attach a single wire from the coil to the module.....effectively bypassing the harness....and the other parts attached to it.

If you note from the schematic,there are other ties to each pulsing wire that feeds the coil...
Should one of those devices be bad(shorted),it could kill the module pulses and easily overheat it.
Let us know which wire it is.....
Example....blue/yellow coil wire does not spark on that coil....Fuel pump relay shorted.
Yellow/blue coil wire does not spark on that coil...tach shorted or it's wire.

These are just examples of a reason the coil isn't sparking....reading volts on the module side of the coil is near impossible...it usually is very low and has just a really fast spike when it sparks...much too fast for any conventional meter...A scope could "see" it tho.
If all this fails,the ignition module may just be bad.
Keep us posted...

It is the yellow/ blue stripe. I cut wire at soldered joint at cdi. Wired a jumper in to coil no fire from cdi on that line. Next step is to open cdi up and find which resister is bad and replace. Thanks for the help it was greatly appreciated. And I am getting the current flow from the pick up coil. Opened up cdi smells burnt inside of it. We'll see where it goes. Might just try to find a different one that not a arm and leg. Do they make new aftermarket ones? Or just have to settle for used? Does anyone have one they would be willing to part with for a decent price.

Thanks Virgilmobile. Both, for helping honker91 and showing me (us), how to. I surely, had no clue. I'm just watching now.
