Bringing the bike to a shop might not be such a bad idea.  At this point you have replaced 2 coils with wires and are looking to replace more parts.  CDIs are real expensive and the regulator is not your problem.  You have been dealing with this for over two weeks now and turned the bike from allegedly running on one cylinder into a no start.

hey howie

got it going...had the ht leads on the wrong cylinders

BUT.... horizontal cylinder isnt firing still

Not cdi`s... swapped them round and both work fine, new ht cables and new battery

Its an electrical problem, a bad wire somewhere

problem is the Ducati shop is really expensive for what they do... for example they quoted me $170 dollars for an oil change!
my honda cbr oil change cost half that!

however, it looks like a trip there is on the cards....

i think the trouble might be the ignition pick up coils ( sensors )

the job insnt too difficult ( it seems ) but do you need to set them ( as they affect the timing, dont they ? )

Great!  when you get that ohmmeter you can check those pick ups, as per my previous post, 95-105 ohms.  Replacement requires pulling the side cover on the alternator side.  Not too difficult, but you need a puller to do the job.  A cheap steering wheel puller would work fine, or you could even make one.  From Ducati they come as a set with the bracket and are pricy.  You can get individual pick ups from  http://ricksmotorsportelectrics.com/trigger-pickup-coils   Do keep the side cover screw in order, they are different lengths.  You need a non magnetic feeler gauge to adjust gap, which should be .6-.8mm.  If you don't move the bracket the pick-ups are on, timing and gap will be as before.  A manual would be a good idea.  The Haynes should work for you. 

You didn't say where you live, but see if there is a local board in this forum for your part of the world, post there and ask if there is a good independent shop.

thanks Howie

i think I will check out the wiring to the pick ups before I buy new ones, after checking other forums, this seems to be a not so uncommon problem on the first monsters ( and even maybe SS bikes )

updates on the way!

cheers

The wires goes from the wire to module to the pick ups.  Yes, the problem could be a break in a wire and be repairable.  Go for it!

ok...ordered haynes manual,  new pick up coils, non magnetised feeler guages and crank case puller.

there is a good thread on here about doing the job but anyone else got any tips/ things to look out for?

thanks

I have a question. Please excuse any perceived sarcasm...

are you just replacing parts or are you testing the items you're replacing because you know they're bad?

There are many common issues on Ducati's, just like other bikes, but the older 2V bikes are really pretty simple if you follow the steps of diagnosing the issue. If you go much farther without diagnosing the real problem it may be tough to figure out what the problem actually is because you may have broken something else along the way.

I just don't want to see you get frustrated and cause yourself extra expense by getting it to a shop after spending money on unnecessary parts.

hey ducpainter

battery..old as the hills

ht coils/leads ..originals from 1997... got 2 almost new ones for peanuts

plugs ... NGK is one of my customers so get them for next to nothing

checked the wiring around the ignition area, no wiring problems there

switched over cdi`s ...not a problem there...

and after looking around on other forums, found other people had exactly the same problem and had happened in the exactly the same manner ..

the bike is a 97 monster and I have had alot of experience with old vespas ( which have always given me electrical problenms ) so to be honest, it didnt hurt to change the ht leads/coils/ battery/plugs anyway

the tools /parts cost less than 200 dollars total so if it is the pick up coils then that is much much cheaper than going to the ducati shop. If it isnt the pick up coils, then I am totally stumped!!! [bang]

i believe dp's point is that if it's not the pick up coils, which you could have determined with a simple resistance test, then you would move on to the next component in the component train.  no need to be stumped.

success!!!

was the pick up coil... this thread was invaluable
http://www.ducatimonster.org/forums/tech/153043-pickup-coil-repair-replacement-pictures.html

big thanks to everyone who commented... i saved around 300 dollars doing it myself and learnt alot at the same time.

granted a simple ohm meter test could have confirmed the coil problem earlier [thumbsup]

next job...replace stock airfilters with twin k&n airfilters

The bike won't run well unless you re-jet the carbs.
