TOPIC:

i have an 82 kz750 H3 thats im having woes with. im wondering how i need to wire it up. do i need to cut it up and use the old ignition plugs and ground? and how come this dynatek doesnt come with a ground? im not electrically inclined, so my friend is doing it for me and he says i need a ground for the circuit to be complete and says that the provided dynatek ignition doesnt have that. but he kinda did a mock hook up today to test to see if we would get spark and the plugs are sparking. is there someone i can turn to on this? ill be contacting dynatek but im hoping i can talk to another person whos plugged this dynatek electronic ignition into their kz750 and knows what to do. theres gotta be, right? -ccentralm

dyna S is the electronic ignition im using by dynatek.

Go to the www.Dynaonline.com website and see what special wiring is required(if any).

Dyna makes several models. For my '77 KZ650-B1 the Dyna model is the DS2-2. If yours is the same then this is what it should look like installed.

there is no ground provided because the ignition plate itself grounds to the engine cases go to dyna and get thier instructions they are simple to follow.

Also, this is what my circuit looks like.



As noted by timebomb33 above, the ground connection is accomplished with the mechanical contact between the Dyna S Mounting Plate and the Engine Case and is held in place with the 3 mounting screws.

Best of success.

ccentralm, do us a favour and add your year, model and location in your signature. It helps get the best responses and is considered real friendly to.

this is dandy advice guys! i went over the trouble shooting guide on dyna's website and from what we've gathered alongside their info it seems to be a wiring problem. it only sparks on 2 and 3 and not on the left side of the bike (left coil) which is 1 and 4. apparently my 82 kz750 ltd already came equipped with electronic ignition??? is there anyone out there with this exact same bike that has done this or bill, does your 77 650 work right alongside my 82 750 as far as the wiring harness and the circuit is concerned??

ccentralm, my "77 KZ650-B1 was manufactured with Points as the ignition control devices. I added the Dyna S (DS2-2) Electronic ignition control devices this last summer along with two matching green Dyna 3 Ohm coils (DC1-1). Oh, what a difference.

But this was only half of the answer. Three summers ago I added the WG Coil Repowering modification. I believe that the associated improvement in starting, running, tune-abilty and reliability are the only reasons I still have this bike today. I cannot recommend this modification to strongly... after 30 years your bike needs this! You will have noticed that it is shown in my diagram above.

I prefer not to give advice on equipment I don't have but here goes anyways... I would speculate that you should remove all of your original electronic ignition system, pickup heads, ignitor box and all. Since the Dyna S has integrated both functions into the pickup heads the installation should be much simpler and cleaner to.

You may have noticed that I installed a new and separate 5 Amp fuse circuit just for the Dyna coils and pickup heads. I did this for the purpose of easy fault isolation and troubleshooting. You may want to do the same since the incremental cost is so low compared to the Dyna parts you have already purchased and certainly low compared to the befits, IMHO.

Now, I will need to let wiser and more experienced KZ750 owners confirm or correct my advice. Thanks in advance.

Best of success.

Still looking forward to your year, model and location.

bill i appreciate anything you contribute.

Did 1 and 4 spark before the installation of the Dyna ignition?

problem solved, im not completely sure what was done but i know the diagram provided was a huge help!

Good stuff!

Thanks for getting back to everyone.

Best of success.
