Title: Ignition coil wiring.
Post by: 671M900 on October 21, 2010, 02:35:01 AM
So, my bikes ignition coils and modules were in a box, new from the dealer, and the coils are dynas. And just my luck, the wiring schematic/diagram in the Haynes manual doesn't match in some places, for any of the years for the m900. How do I figure out which goes where? The wire from the pickups don't match the diagram, is there any way to figure out the orientation of the pickups? Are monsters waste fire system?

Which pickup corresponds to the vertical and horizontal cylinder? One pickup plug's wires are longer than the other, so I assume it goes to the far end of the bike, which is The right side coil.

Looking at the dyna coil install page at ducatitech, it seems the wiring harness that is displayed there also doesn't match the Haynes, haha!

Thank younso much in advance!

Checked workshop manual, not much help there either.

On mine, looking rear to front, right is for front cylinder.
So, longer (as you noticed) 2wire pickup wires to that ign module, right coil same & that coil plug wire to front cyl. For colours I need to get to garage which may take a while.
IIRC....

Not much happends if you get this wrong, just sounds funny & won`t start.

+1 Us 'old' Monster guys (the bikes) gotta stick together 8)

The diagram for the Dynas shows the connectors for the bottom of the coils are different sizes to match the 'female' connectors on the wiring if that helps. The wide tab connector is + and narrow - according to the Cal Cycleworks instructions. Ducati Suite site has good pictures of the wiring layout and check the Cal Cycleworks site. The length and bend of the loom gives a guideline unless it's been messed with.

came across this:

but it seems to me like he's reversed the coils around to face the other way? I also noticed that for the pickup wires, there is a black loom guard and a white one. this is most likely the key, black is left or right?

Yeah I'm pretty sure he reversed the ignition carrier coz it's now facing the front of the bike.

Now, the question is if the right coil still controls the front cylinder, haha!

Yeah, probably when looking from the front (maybe). ;)
Waiting to see when you fire her up now [evil]

I wish, exhaust gaskets are on the way, but the damn half bushes are on order from ducati italy. Also in need of a fuel line valve apparently, other than that, I'm fidgeting everytime I think about her, hha!

If anyone can take a peek at their wiring, and tell me which two wire pickup is attached to which cylinder, black or white, I would really appreciate it! Also, which module is the tach harness plugged into?

Further digging into the shop manual, not the haynes, reveals a green brown wire, not a green black wire as shown in the haynes manual. Luckily, a green brown wire is what I have. Actually, I think that the "black" spots on the green lines for the wire are just poorly colored brown, haha.

EDIT!!!!!

I guess we'll mark this as solved, if I get confirmation.

(http://www.ca-cycleworks.com/shop/catalog/ducati/img/dyna_kit.jpg)

Upon really close inspection, white loom from the pickups controls the vertical cylinder, and the 3 pin terminal has a grey wire, which in the haynes and shop manual schematic, controls the horizontal cylinder. Also, greenmonster confirmed that left coil controls vertical and right coil controls horizontal.

All I need is confirmation that the middle wire in the left ignition module is in grey, as the pictures aren't as clear. Sent an email to chris at cycleworks, though.

On mine, both modules have black-grey-red (L -> R) on 3pin, seen from rear to front w modules
as original above battery.
My RoadRacing tach had wiring t HZ (R) ign module but I can`t see that it matters which.

Hmm, i see. However, I think that the pickups are more important than the 3 pin, as I suspect that the 3pin just provides power, if that makes sense, and the pickups tell the ignitors then to fire. Thanks for the input.

Makes sense. More important? Well....
Just mate the correct coil & plug wire to correct pickup when you know which belong to HZ & V cyl.

3pins don`t have any wiring into them?

3pins have wiring, but they go straight to the 2wire plug on the harness, one goes to ground, and one goes to power source. Red wires on the three pin mate to brown on the harness, meaning red wires in schematic are brown. Middle wires on my harness are grey and green/brown, which according to the schematic in the shop manual, are left and right respectively.

For the pickups, I just went with the picture from cycleworks. What I want to know is which cylinder is connected tot he pickup wire with the white sheath, and which one has the black sheath.

So... semi solved?

Semisolved.
Made small mistake about what module should be R & L. Not that it matters as long all is correct connected.
My set up w the FCRs are opposite original, which had HZ L.

Guess I need to get to my bike to really check but too much work right now.
Maybe you can sort out some other things til then, think also someone else could chime in, koko?

Just got in from a ride through the local hills. Checked the thread.

Popped the tank and looking from the back of the bike, with the stock air box bracket and ignition placement (I run a chopped lid & K&N).

Left coil and ignition box have the white, 2 pin cable wires, they go to the horizontal/front cylinder.

Right coil and ignition box have the black, 2 pin cable wires and go to the vertical/rear cylinder.

The dyna coils wiring is self explanitory due to the different sized connectors.

I realise I had put a dot of paint on each relevant connection for future reference.

Hope it's of some help.

YES!! DMF comes through again!  What of the 3 pin wires?

Back to the shed.
Looking from the back.
Red black and green/brown to the Left box and coil.
Red black and grey to the Right box and coil.

Mines a '95 model. Hope it's the same.

Was in my shed &, sorry,
different wiring colours so I can`t help. EU vs US I guess.
Only thing, the white couple to pickups were significatly longer.

Thanks for the help though, I do appreciate it. If anyone as the time to pull the cover and verify which pickup goes to which cylinder, that would be great, however, I think the way I have it, as per the diagram in the Haynes an shop manual should be fine.
