So I pulled a freshly cleaned plug to install and try again and noticed something as I got it in but accidently hit switch with hand still pushing cap onto plug. Wiggle one way....crank...other....nothing. yet every single test on the head showed spark. So I looked into how our plugs are designed...then took it apart that night and seen how cheap our part manufactures actually are. We get a quarter inch thick cable with a mere 1 to 2 mm of copper within. Yea....even the so called Orange performance coil. Another strategy is to just initially try replacing the plug cap to restore continuity . . NGK 8052 for 139QMB.   |

Not to be repetitive but... 1Muskrat, my fox body Mustang, needed my help this morning. It seems he got some plastic stuck in his teeth from his morning breakfast of camaro.

OK. I figured out to check the page # on the post before replying. Oops.

I was thinking of getting spark quicker and stronger to plug i got 2x coil and leads was thinking of shorting lead to plug can this be done you would have to mount coil nearer plug of course but does extending wires from stater to coil length mater  |

Lost, can you show me schematics from anywhere that show the 'inductive' and 'transformer' coils?
My experience is that a coil is a transformer. It steps up (transforms) lower voltage to higher voltage.
A DC coil works as you note, creating a magnetic field in the lower voltage winding which then collapses, lines of force(magnetic) cutting the conductor(wire windings) in the other coil. The fact that there are a LOT of conductor windings being 'cut' by the collapsing field make the voltage much higher.
An AC coil is just a normal everyday transformer, the same as a DC coil being fed AC current. As the voltage goes from hi to zero to low to negative, the coil will fire for each field collapse, or generate current flow in the secondary winding. In the case of a normal use transformer, voltage can be stepped up or stepped down. A welding transformer will step the 110/220VAC down to the 30's(more or less), but the amperage will be multiplied. If an ignition coil, a specialized transformer, is fed AC, it will generate higher voltage as the voltage being fed to it cycles from low to high and back to zero, voltage generated on the 'sweep' of the voltage rising and falling. I do not think it will generate as 'sharp' a spark as one fed DC, as the field current is removed abruptly, but may have to consider more on that.
I do not know the difference you are alluding to, but am open to new to me things.

Auto mechanic fir 25 years and that's fir sure a ford coil used on most fords and there's two wires b+ key on and ground is the signal. And also someone was asking above about how a coil works its fed key power and when ignite or whatever it is that is controlling it grounds it. The amount of time the igniter grounds it for is called coil saturation. The coil fires the exact time the ground is removed but internally it works Luke said primary windings and secondary windings. When the ground stops and the magnet field colaspes is what makes the high voltage. I use ascooe at work and a ford coil draws about 9 amps and makes I've seen up to 30 kila volts.

Ancient history, but a question. If a coil gives a more powerful spark, would a larger spark gap yield better or faster combustion? Would a timing adjustment assist?

Well I installed it this morning, put the round tip back on the end of the plug, B+ to signal and the other wire to ground. It was a cold start (44°current/38°low) this morning and fired up on the second kick. I just installed a new carburetor so not sure how much of a difference it made on cold starts. I don't plan on riding till this afternoon and it warms up. I'll report back on my thoughts. I bought the wire harness online for $4 and the coil from AutoZone for $21.99.  👍 ![]()  Update: Noticed a slight performance increase in acceleration and idling. I'm glad I did this. Those cheap Chinese coils plug boots tend to fall apart. I've had to replace several due to the plastic breaking or the connector wearing out. This makes a better permanent application. |

I'm a auto mechanic and I've been wanting to try that since I saw the ncy cop. I'm in now I'm gonna do it this weekend

U can also get a pig tail connector for a ford coil from the parts store this way ur not using cheesy spade connectors to the coil I'm doing mine this weekend

It's pretty self explanatory once you physically have the components on hand. IIRCC there was a brownish-red (hot wire) and a white/black (ground wire) on the one I snagged. My scoots wiring harness & terminals for the coil are black/yellow (hot) green (ground). So just hook em up and done. Yeah, but it's not OEM and there's no wires that came with it. Does it hurt anything if I just plug it in randomly and see if it works? |

Sorry to bring up an old thread, but could any of you fellas post a pic on mounting the coil? Sure would like to see some mounting ideas.

you would need to prove this mod enhanced your power on the dyno, tbh.
I see no way that this is better than a scooter coil, because they are both quite literally the exact same setup.
if anything, the scooty scoots main difference is they have a lot more Hi-Potting inside of them to protect the coil from the elements.
plua the scooty scoots fire at 10k+RPM
A ford victoria was never designed to do that.
at the end of the day,
primary coils and secondary coils are just coils.
all coils are basically the same.

I came up with this mod after seeing that ncy offered a coil on plug upgrade but I didn't want to pay the price tag. The benefit being a more direct, quicker and stronger spark to the plug. There is no special wiring necessary, just have to make the bracket to valve cover and trim the rubber boot. Oh and it's a 2000 or newer Ford crown Victoria ignition coil. And yes this works and very very well!!!! In my zico simpli 2t 1e40qma I had a problem with interrupting when starting. Lots of adjustments to many carburettors and replacing all of the electrics didn't help. Even the n-naraku coil did nothing. I installed the DC coil dedicated to the Ford Brown Victoria. The engine works beautifully, better spark, much better mount for the candle than the traditional cap. I recommend and thank you |

The first thing I noticed about this mod was the starting, no hesitation, crisp clean start. The second thing was that my bike was smoother riding. The thing used to do some kind of backfire when letting off on the throttle. That is gone. Faster? Not really. Maybe 2 or 3ph...maybe. After riding a little while you just get a feeling that your ride is...more solid...better. I think that someone posted something like it burns most of not all The fuel in the cylinder. That's what it feels like.
Installed on a 2020 Soleil with a 50mm bbk, À9 cam, performance exhaust, stock variator (kept breaking performance and racing types), blue cdi and other things I cant remember.
...and remember to upgrade your suspension.
