3ohm green coils

I got them installed and they work great. Bike seems to run better. I clipped off the ends of the old wires and crimped new caps on them. The wires were new. I had to grind down the mounting brackets on mine to install the coils. I also used shrink wrap to protect the wires from hitting the frame. It worked out really well but would have been better if I could have used the second holes.

Nice job making a new bracket. I didn't bother creating a new bracket, but there was precious little room for the Dyna Green in the stock coil location on the 650G. I certainly have in mind that I'd like to improve the mount at some point.
 
I was riding back home from a short ride and bike started running like crap. I checked the bike when I got home and 1 coil was bad it was the secondary circuit. I have got a used on off ebay on its way to use. I'm not sure what happened to it. The plug ends are nkg, not to old.Everything else seems okay? I'm wondering if I should check anything or is this a problem with aftermarket coils. They were running great.Thanks for any info.
 
It would be hard to tell what happened. Personally I would dump the cobbed wires unless they are copper and just spend the $17.00 for a good set of Dyna 8mm suppression wires at Z1. If your wires are not copper, you are putting another resister on resistive wire with the plug caps.
 
I'm with OldVet66. Put a quality set of suppression wires on there, and ditch those expensive suppression caps. Easy peasy.
 
I think I will, I probably should have done that from the start. They are copper wires though. They have them on ebay also. I will get me some this weekend either way. Thanks
 
save a few bucks shipping that is all. If I needed more stuff right now no problem. That is all.Those are 7mm some were saying use 8mm? That is why I ask. I thought the coils came with the 7mm wires. Does it matter if you get the copper ones?

The 8mm are suppression wires and do not require the PITA ceramic resistance caps. The 7mm shown by BigD are copper core and require the expensive ceramic caps. Do yourself a favor and get the suppression wires and give the ceramic caps the boot. Double entendre' intended.
Z1 does carry the suppression wires also, in both sizes.
The eBay seller does offer free shipping.

Thanks for the information KK. I didn't know that about the 7mm wires. My understanding was they (suppression caps) were not needed on these bikes, and everything required came with the 7mm wires.

Does that only apply to bikes running the Dyna S ignition?
 
Dyna sells both suppression and copper core wires in the 7mm size. The one you pointed to had copper core, which require the ceramic resistance caps. For my money, the caps are a waste of money when you can purchase the same diameter wires with suppression wire, thus eliminating the need for the special caps. If you parse through the threads in the electrical section, one of the first things we tell folk with copper core wires is to trim back a bit of the wire because they tend to oxidize over time. The suppression wires eliminate this possible point of failure.
 
That makes sense. I'll have to look back at my orders from Z1 as I must have bought the suppression wires...on your previous advice, KK.
 
There ain't no free lunch, though; suppression wires with a cheapskate graphite core are much more prone to internal failure and many auto makers recommend they be replaced every two to three years as a service item. Having been let down in the past by graphite-cored HT leads, I wouldn't touch them with a bargepole.
If you really want to be relatively immune, go for double-wound wire core, silicone insulated. I fitted these recently and was slightly sceptical of the inbuilt low resistance (about 200 ohms per foot, iirc) being sufficient suppression for RF. It seemed to be, as when I had the bike running, there was no workshop radio pickup, but I wasn't really looking for that, being busy with the bike. Even if it was insufficient, there was also the possibility of retro-fitting with NGK suppressive caps or resistive plugs if I had to.

Another thing to consider is this:
Those expensive ceramic caps are really there to suppress EMI. That is, so your bike's sparks do not interfere with radios and stuff. The best way to go is copper wires with straight caps, and to heck with the EMI.
My Accel coil kit came with quality suppression wires, and I never had any issue with them. Cheap wires, sure. Quality wires, well, that is what your automobile came with. When is the last time you changed plug wires on your car?
 
This is the stuff I used but mine came in a ready-made set as NOS designated for a fork truck, at likely some outrageous price originally.
I'm quite happy with it, and given the hassle I had trying to find ordinary HT lead locally, I think I'll just order more of this stuff online for the other bikes.

When wiring these Dyna coils on an 1980+ year bike, are they just plug and play or do you need to add a relay?

In reality, a relay is more of a workaround when you are seeing voltage drops from battery to coil. You do not NEED a relay, but the coils are not simply plug and play. You might have to rig up new terminals and/or modify the way you mount them to the frame, as they do not necessarily perfectly line up to the brackets.
