You tried the switching the wires? Only a really a couple of ways they can go with the different sized connectors. It only swaps cylinders/coils not ground or anything. The different sized connectors give some measure of protection. I did the same with no blow ups, just bad running, as long as your grounds are good.

Thanks to Speeddog for this info that he provided me in an older thread, it was confirmed to be accurate at the time.

"Left side"
Ignitech 2-wire white plug (blue and brown wires) connects to red/white trigger wire.
White plug with white wire to black/brown/red on bike harness.

"Right side"
2-wire black plug (blue and yellow wires) goes to black/yellow trigger wires.
3-wire black plug to red/gray/black on bike harness.

Dont forget paint dots on the connectors.

still no spark. :( I'm going to proceed as if I either completely imagined hearing the bike briefly run or that I may have disconnected to ignition harness and reconnected it improperly.

Here's a photo of my hookup;



Brown/white&blue/black are the wire colors of where I'm connecting the ignition harness to the main loom. The 2 mystery lugs are now secured to the respective coil brackets. Main ground strap is secured to the neg battery post. All fuses double checked. All wiring to the Ignitech triple checked.

Tested with known good units (Kokusan boxes). Still nothing. :(

I still think it's a ground issue...

If you use an ohm meter between any ground lug on the harness and the engine do you get 0 resistance?

Can you explain...? I have a reaaaally crappy multimeter...what should I touch the 2 test leads to exactly?

Could the rectifier be the culprit?

It has an ohms scale...correct?

Touch one to one of those ground lugs for the ignition coils, and the other to one of the head nuts/studs.

If the reading isn't very close to zero I believe you've found the issue.

OK I see what you mean now...

...just had a thought...and I'm not at the garage...but my coils are very loosely screwed to their bracket...via stainless or aluminum  (can't remember which ones I ordered from McMaster ) coupling nuts, which are attached to a heavily powder coated bracket. Now those wires with the small lugs that we were wondering about, I now assume those are ground straps (although they're awfully thin for that)

I guess I'm now wondering if this is where my problem lies. What's the protocol for securing the coils "properly"?

Here's the deal...

You have a freshly powdercoated frame, and a freshly painted engine...

and I'll bet money, I'll send you the address to send it  :-*, you didn't clean mounting surfaces for the engine, or use toothed washers for any of the wiring that is establishing ground.

You'd be wrong about cleaning the engine mounting point under the lug. :P did that.

The frame is painted from the factory...it's a NOS frame. And...I don't have an earth cable to it at all...I felt that the strap from the neg battery post to engine would suffice...and obviously the engine is mounted to the frame via 2 big fat 10mm bolts...

So...tomorrow I will;

- replace the OE neg battery cable which looks to be a 6ga and rather old with a fresh fat 4ga, this will run directly from my neg battery post to the motor.

- add an additional strap from motor to frame (is that really necessary? )

- route the grounding lug from the loom...where? It currently is screwed to the neg battery post along with my main ground wire to engine. Is there a better idea? Is it supposed to attach to the frame?

- what's the correct way to mount my coils?

The whole deal with having the motor briefly crank really bugs me...wish I had a spare set of coils...

Thanks again...

I've been wrong before, ask my wife, but without an ohms reading between the wiring harness and the engine you can't be sure the engine in grounded.

A factory painted frame...did you clean the paint off the mount points? The painters typically don't care.

Is your motor not painted from your engine guy?

You left off the ground strap that Ducati used.

If you ground the motor to the battery you neglect the harness. There isn't necessarily a good connection between all the components.

Use your meter and find out, and then go forward.
