Mount Dyna coil DC1-1?

I installed the Dyna coil DC1-1 on my Xj 650, and since the wire connectors are on the sides, the tank doesnt fit....how has everyone else mounted these coils on their bikes??

 

Lots of finagling and usually by constructing your own mounting brackets.

 

I'm not familiar with the differences in our bikes but have you seen the Maxim X page and his setup for the dyna coils?

Check it out here if not: Maxim X Resource Page-Dyna Coils

I haven't tried it as of yet, but plan on doing this mod in the future.

Good luck

 

3" hose clamps. One around each coil between the poles and tightened so they do not move. Angle the coils so the the poles are pointed at an angle towards the center of the bike, then there should be no problems. Kind of ghetto but it works well. cruzerjd

 

thx for the help! I was thinking about trying hose clamps....wasnt sure how good it would work.....

 

I also just got a pair of DC1-1 coils for an early christmas present. I was thinking I would mount them where the stock Airbox used to be. I haven't cut and sized the plug wires yet, so that should not cause an issue, and building a bracket shouldn't be too difficult.
Is it really as easy as just hooking up both wires to the new coils (no polarity worries) or did I misread the directions? Where do the wires going to the coils come from? I assume the ignition box, but I don't really want to open up the loom to find out. I confess, I can't often decipher wiring schematics without sensory overload.
The reason I was wondering was that if they do terminate at the TCI module I was thinking I may just hack in right at that point and run new wires to the coils under the seat. I could then just leave the old wires in place in case I ever want to replace the airbox or go back to stock configuration.

 

I used bailing wire to temporarily hold them in place for the first week or so, just so I could test them out. Then I fabbed my own brackets.

 

Please don't..........

There ya' go!!!

Put the wire cutters Down and s-l-o-w-l-y take a step away from the bike.

Yes, that easy! Yes, they come from the TCI!---and orange/red-white wire to one coil, and a grey/red-white wire to the other. There should already be those wire leads and a terminal connector in your harness, with those colored leads, living somewhere around where the stock coils live.

Good threads about these coils here:

I put Dyna coils on my 750 Seca and there was only room for one coil in the stock location so I had to mount the second one farther back under the tank towards the seat.

 

I hate to be really oblivious, but I guess if it's working I haven't had to worry about it. Dyna coils change the 12v to much higher to create the spark we need, what do we have in it's place right now, and where would I look to see it? Are there pics in a post I haven't found yet? Thanks for patronizing my newest learning curve.

 

If you bike is hard to start or dies when it's humid and your coils are cracked like mine were it's time to change them and if you are changing them anyway you might as well get better ones. The original coils make a pretty weak spark so the bike is hard to start when it's cold and the battery is a little bit weak. With new high output coils it will start any time you have enough battery power to turn the engine over.

 

doesnt the meatal mounts on the coil have to be grounded to the frame in order to work? How would a hose clamp wrapped around the outside of the coil allow it to be grounded?

 

Quick answer: NO. The "coil" grounds through the spark plugs..........

 

That's correct for the high voltage side of the coil. The low voltage side of the coil is grounded by the TCI. When the TCI grounds the circuit, a magnetic flux builds in the primary coil. When the magnetic pickup senses the reluctor ring, a small AC current flows to the TCI's circuitry. The TCI opens the coil's primary circuit. This causes the magnetic flux to collapse cutting the wires of the secondary coil, inducing a current. Because the secondary coil is wrapped at such a higher ratio to the primary, it steps-up the voltage. As chacal mentioned, the ground for the secondary coil is through the spark plug. To get there, the voltage must be great enough to jump the gap.

Class dismissed.

 

Has anyone tried the ignition coils by Nology or the other brand that is listed in J.C. Whitney? They say that they work with the Maxim's but no specs on output. Single or Dual post. They also have "split fire" spark plugs. Again, has anyone tried these?

 

I've never tried split fires in a bike, but the store I worked at sold them, they are a gimmick. The spark will jump from the center electrode to one side or the of the V and then wear that side down until the other side of the V becomes more viable for spark, then that one wears down. They give you no benefit, and they wear out much quicker
