That's what the wires are for...to provide a ground because the plastic can't. How did you confirm the ground?

On the Monsters of that era Ducati grounded the frame to the engine with a braided strap by the right rear set. All the chassis grounds then connected to the frame.

If you didn't scape all the paint off the engine mount points on both the frame and the engine your ground wire from the battery to the engine does nothing because the engine is electrically isolated from the frame..

Where does this redundant wire run from and to?

Did you take a resistance reading from a head stud to any wiring harness ground like we asked?

I just finished rewiring the entire bike with the old school 90's harness from my parts 750. I wanted to use the simpler coil wiring that didn't have those stupid lugs. Bike has spark now. I don't know what the deal was before and I don't care.

That was pretty annoying actually...getting bested like that despite all of your best efforts to help me out. I would have simply swapped the coil and ICU wiring but the connectors were different. That older harness is significantly simpler tho...much easier to route and quite a bit smaller so it turned out ok I guess. Thanks again, sorry the effort was wasted.

Glad things are sorted.  Wish I could have posted back sooner.  As far as coil testing goes, normally you would test the primary by going from small connector to small connector and secondary from tower to either small connector.  I looked in the manual for coil specs since Ducati coils spec differently from most coils.  Their directions say tower to ground.  This seemed weird to me since that would indicate a winding that was shorted to ground.  I think you may have proved they are wrong.  An ignition coil is just automotive terminology for what the rest of the world calls a transformer.  Sorry for the confusion.

No, you weren't bested.
You won the last round.
And some of us lurked and learned a bit more.  :)

I just looked at the Haynes manual.  They got coil testing right.

All that's really standing between continued tomfoolery and riding is basically :

- Fuel hose plumbing
- Shoring up a few random things, cleaning up the wiring etcetera.

My next questions deal with critical safety issues...primarily the wheels/axles...my Carrozerria wheels didn't come with instructions...just a set of bearings and a pair of spacers. There was really one way to put them together and it went smoothly but I'm still a bit nervous so I'm going to post several pics later today and get feedback from the lot of you. And there's a concerning lack of thread on my rear axle after the billet chain plates and Ti nuts. Tony tells me this is normal...but I'd def prefer as many opinions as possible here, lol.

As long as the threads of the nut are fully engaged it's fine.

The TPO Ti axle nuts have a thicker flange and barely leave a thread showing or just about flush. You really have to have the axle centered evenly or one side misses out. You'll never round those nuts though and they stay clean.

They aren't. I'll post up pics later but I'm pretty sure I already know the answer to my question. Love the chain plates and the Ti nuts bit not going to compromise the safety of myself and others for it.

Well, good news and bad news. Good news:



Bad news is I have a moderate leak at my center case gasket. I'm not panicking just yet, because I wanted to see if this is somewhat common on a fresh motor build until things "cure", and/or could be a simple issue of retorquing some bolts. Engine is hot as fuq so I have time to kill...

Once the axle nuts are torqued, the rear wheel ceases to spin freely. I've just finished taking it apart to check how I've installed the spacers and caliper bracket and everything seems to line up and fit perfect. Spacers were idiot proof, they only go in one way. The wheel, spacers, and caliper bracket felt like the perfect amount of friction...just a bit of nudging around with my knees and a few light mallet thuds. The wheel moves fine by hand it just won't spin freely. There is no sign or feel of any lumpiness or drag...just a consistent friction that prevents the wheel from spinning freely. This may be normal on a new set of wheels, spacers, and powder coated swingarm and may "break in" after the first ride but I wanted to get a second opinion from you lot.

Thanks

Possible brake drag?  Can't tell much over the internet.

Oh I understand that. The rear brake isn't hooked up neither is the chain.

Figured it out, missing an inner spacer.. :-[ too bad I destroyed a wheel bearing already  [roll]
