3rd failed ignition module?

[Pu241]

Not a problem, want to know what's going on myself!
We have too little hard facts, just trying to add one more fact to the list.

[mattdickmeyer]

the pick up coil is a low voltage component, that low voltage is then converted to high voltage by the secondary coil the condenser has a specific level of resistance for that specific currant ,that said , failure of that condeser can cause his problem , I to am educated as we all are , just helping helping this fellow out as this is what I do 12 hrs a day.

Take a look at the wire wound up in the pickup coil. It's finer than the hair on your head, it has to be low voltage. It wouldn't ( and evidently doesn't ) take much to ruin it.



These are two pieces. The ignitor can be found but is expensive, the pickup coil ( if you can find them ) is $40

I forgot to mention... This is my ONLY mode of transpo. right now and I have an interview tomorrow morning that I HAVE to get to.... Please help ASAP.

oh, and by the way, good luck at your interview

Trying to figure this out as well, what's the status on your suppression capacitor? new-old-none at all?
It's been called many things... but this is what it looks like....this one is missing the wire.
Some say that all this thing does is suppress engine noise in the radio, but I believe that it also sucks up excess voltage that the coil produces, and the disty wont take. If its bad then the coil burns up the pickup coil.
These things always have a fracture in the wire insulation where it meets the capacitor. It may look like it's good but maybe it's not.
It would be nice if we could find the real meaning of this piece and where to get one new.

no, has absolutely nothing to do with the secondary side of the coil, or flyback voltage to the module. It is a radio noise suppressor, as you first stated. It prevents the reverse flyback voltage from flooding the ground plane, which causes a whiring noise over the radio speakers. That's all.

However, how is the ground strap on the engine? It goes from the right strut tower to the back of the cylinder head.

FB71, What are your credentials?

jmye1524's called this one for you, removeal of the condenser is allowing excessive voltage to your primary coil, this is causing your ignition component failures. this will fry your pick up coil as well.

dear god, no!

Capacitors do NOT pass direct current, but they do pass alternating current. The capacitor is connected to the POSITIVE side of the coil and GROUND. As Pu241 stated, when the gauss field of the coil collapses (generated by allowing direct current to flow thru the coil's primary windings), it cuts back thru the primary windings, generating a reverse polarity current in the primary windings. This can be as high 20-30VDC, but microamps (millionths of an amp). The capacitor has a static charge (like a balloon thats been rubbed on your hair), with it's potential in the source polarity. Introducing a reverse polarity pulse (or a sufficient pulse of either polarity) on the source line generates EMF radiation (ElectroMagnetic Frequency) on the source wire. This has NO EFFECT on the components attached to circuit. Devices that read EMF (radios) pick it up as background noise, the amplifier stage in the audio unit makes it audible as a whir or pop. The Job of the capacitor is to cancel that EMF pulse as close as possible to the source (ie; coil), to prevent the circuit feeding the coil from becoming a transmitting antenna. If the capacitor is not there, you still have circuit suppression, THE BATTERY! It acts just like a REALLY BIG capacitor. The only difference is it's proximity to the source. The pulse has to travel (at near the speed of light, mind you) up the source circuit to the battery for suppression. This turns the circuit into an emitting antenna, and we hear the resulting noise on the radio.

I teach this subject nearly every day.

Can you teach us whats going on with our pickup coils/ignitors?

I'm trying to devine the answer. It would help greatly if I had the offending coil and modules to evaluate.

ROFLMAO! Jim I dont think anyone has called you out for your credentials before!

WOW! I am glad we have someone with the knowledge and expertise on this site. It is a little too technical for me to follow, but I got the idea that it has nothing to do with my problem whatsoever! Thank you for shedding some light on the situation Jim. Any expert opinions on why I am burning through them like water?

[FB71]

legitimate question. He's trying to find concrete answers to a very annoying, and progressively expensive problem!

I'd love to test your failed units against my known good used and new units, as well as put them thru a series of 'stress tests'. PM me if you're interested. No difinitive recommendation yet. Have you verified the condition of your ground strap?

You've got them! I have a disty coming to me tomorrow, and I will get a coil while I am there. If you want them for some kind of study, I would be more than happy to donate them to you for diagnosis! I just don't want to kill another one... this whole new (refurbished) disty just cost me $150! I am not going to shell that out repeatedly!

Have not checked the ground strap... not really sure what you are referring to.
