ERR...looks like i screwed up lol. i drove it around...lacked a lot of power, figure maybe i got the plug wires backwards for the leading..swapped them...no difference... errr ok. so i get my volt meter out...power is going from stock coil to FC coil at 14 volts...k...pull a plug out while attached to LEADING plug wire and ground it and try to start...no spark at all. switch same plug to a TRAILING plug wire from the dizzy and its sparking. i must have wired something wrong inside the FC coil...i'll take pics in a few. and btw, yes a 12A can run on 2 spark plugs just fine just back fires a bit...and sucky power..haha

 

any help here? still not getting spark...and im still wondering how this FC coil gets the signal to fire..when the dizzy isn't conected to it at all..

 

Oh my.

The dizzy needs to be connected to it. The leading magnetic pickup's green and red wires still need to go to whichever ignitor you chose to use. Then the ignitor's C and B wires go to the - and + of the coil, respectively.

 

huh?? nobody said that..lol. all i have is what you see...in adition to removing the ignitor from the FC coilpack and making the appropriate connections. how do i link it to my other ignitors?? (scrounges around through other pics...)

 

i see people talking about wiring it to the FB ignitor..but i can't find pics...ahhh..help meh. lol. i've dont everything that 85RX7GS has said..(i think) but i dont remember anything about linking up to my ignitors. this had to be why im not getting spark...pleas help

 

Ok. Leave the leading ignitor on the dizzy in the stock position. Move the wires from the old leading coil to the FC coil. The ballast resistor also needs to be in the mix. That should do it.

 

Ok. You have already made the connection to the ignitor when you jumped the wires over from the old leading coil. The negative is the trigger from the ignitor. Don't worry about that.

BUT, leaving the old coil in there wasn't a good idea at all. That means the ignitor is seeing current from the primary circuit of BOTH coils and might not be able to handle it.

First get rid of the old coil (run the wires directly to the FC coil) and then see if the ignitor still works by swapping it with the trailing. If it does then there's probably something wrong with your wiring.

 

REVHED is certainly right about that - you don't want to be energizing the old leading (FB) coil anymore, so it's best to remove it from the car all together and utilize the "+" and "-" terminals that were screwed onto the posts. I guess I forgot to mention that part or didn't explain it well enough, sorry The negative on the FB coil has a slide-on connector, which I believe is a yellow wire. Remove that from the FB coil and hook it directly to the negative on the FC coil. FCDFIS works by using the single leading J-109 ignitor to fire the FC coil. If I only had some way of digitizing my sketches, I could show you my diagrams and schematics for the ignition setup. Hope that helps

 

well...i swapped it back to the standard so i can make it to work tomorrow hehe. only thing i need to know how to do is use one of my existing ignitors to fire the FC coil...and yes, the negative has a plastic clip. so i should snip off the plastic clip, and connect that wire to the negative of my FC coil, same for the positive that went to my FB coil? as for the ignitors...i removed the ignitor from the FC coil and wired it up as mentioned. so basicallly inside the light metal colored part are just wires...no ignitor or that white thing..whatever it was. if i can just figure out which of the 2 stock igniotors to wire up, where to wire them, and how to the FC coil..i'll be good to go.

 

It's very simple. Just disconnect the positive and negative wires from the old leading coil and connect them to the FC coil. The ballast resistor goes in line with the positive wire.

There's no need to touch the stock ignitors or anything else.

 

that's what i did...ballast resistor? where is that..hope that isn't the white thing that was next to the FC ignitor. i cant get any spark from my FC coil though...how is it supposed to know when to fire?? the FC coil has no connection to the dizzy whatsoever..and im thinking there's supposed to be.

 

So how do you think the stock coil knows when to fire? The negative wire runs through the ignitor and is what triggers the coil. You simply take the positive and negative wires off the old coil and connect them to the new coil. It can't get much easier than that.

If it's wired up correctly and not firing then you probably blew the ignitor. That's also why you need the ballast resisitor there so it doesn't draw too much current.

 

where is this ballast resistor?

 

You can find the ballast resistor by taking the back off the 2nd gen ignitor housing. It's the white rectangular dohicky.

 

err..i didnt wire that in when i removed the ignitor..that went with it. it was originally on my yellow wires though..not the black. where should it belong?

 

*holds ballast thingy in hand...* err. WHERE DOES IT GO...

i've got...yellow to yellow, 2 blacks to 1 pink, and this ballast sitting by itself.. the yellow originally went to the ballast.

 

is that what mine should look like? (minues the ignitor)

 

The yellow originally went to the ballast? WTF?! Did it look anything like the picture I posted above? The resistor should have had two black wires attached to it.

 

err...yep. yellow...my black wires look like your yellow, and vise versa.

 

hmmm..... perhaps the assembly guy was drunk that day!

In any case, snip the resistor out of there and throw that 2nd gen ignitor in your parts bin. With resistor in hand, splice it in-line on the plus side of the coil. Got it?

 

err..the yellow wire right?

 

It doesn't bloody matter what colour it is! Splice it to whatever the positive wire was on your old coil and connect it to the postive terminal of the 2nd gen. coil.

 

how the hell do i tell what positive is on the FC coil? lol they aren't marked...

 

The coil is marked. look carefully

 

uh oh..think i found the problem. well..i wired up the ballast, reinstalled the FC coil, only this time...put my pos and neg on the TRAILING fb coil...fired right up...so THAT works. but before i hooked the wires up, i could see a spark in the coil..so i knew it was firing. as for the leading coil...it just sits there. anything i do with it and nothing happens. while it was running..i unplugged the ignitor to the left( standing on driver side of car) no change...pull the one on the right, dies. so i think ok...i get out the voltage tester while the car is running, and the left ignitor is doing NOTHING...last night when i returned it to the stock wiring setup, it was still only firing 2 plugs. so..my guess is when i forgot to wire up the ballast when i hooked it up to my leading FB coil and ignitor..wham. does this sound likely? and would anyone like to sell an ignitor? hehe.
