how to check stator output

[alibaba]

2009 696 Monster  -  I know I am to take readings at the three yellow stator wires where they connect to the rectifier.
#1 - what rev range should I use
#2 - what reading should I get
#3 - do I leave the yellow leads connected to the rectifier and
       just check voltage between there and ground -  or disconnect
       leads and check to ground?

dont worry. Howie will be along soon.
he has your answer.

This is what I PMd alibaba:

Before we go any further, your bike is under warranty.  Your role as the customer is to state your complaint and supply as much information as possible about the symptoms and conditions, ...actually even that is there responsibility to know what questions to ask.  It is the dealer's job to do the diagnosis.  If you tell them what to do and it doesn't work they can bill you for it.  If you break or damage anything  it is your responsibility.  If you can not get satisfaction out of your dealer you need to go to another dealer, call DNA, or do both.

Anyway, to check stator output, follow the three yellow wires from the alternator.  The wires will come out of the left side engine cover.  You will come to a connector that leads to the regulator.  Disconnect the connector.  Each yellow wire is one phase of your 3 phase alternator.  Connect the voltmeter, positive to each stator wire, negative to ground.  You should get 27+10V at 2000 RPM and 78+V at 6000 RPM.  If you are getting  14.5 volts +.5 to the battery at 3000RPM there is no need to perform this test.  One test that is often overlooked by motorcycle shops is battery drain, or the more correct term, parasitic loss.  This is what the bike uses when parked.  Ducati has no spec for this.  A good "anycar" spec would be less than 6 milliamps.  My educated guess would less than 2 for your 696.

Hope this helps

Thanks Howie  -  exactly what I needed to know.  And nice info on the parasitic loss.  I am losing @ .01volt a day over 5 days now without the tender  -  i think the new battery (warranty) has solved my problem.  Just thought I would check the charging system out to be sure its up to spec.

Hi Howie,

I respect your knowledge and experience but I'm not sure I completely agree with you about leaving things up to the dealer.  Of course if we as bike owners screw something up while a bike is still under warranty, it's likely going to be on us to foot the bill.  However, in most cases I really think it's a good thing for us to do as much diagnosis as our knowledge and tools allow and be an educated buyer when dealing with dealer warranty issues.   Especially in a case like this where his dealer has told him that it's normal for the  battery to be dead  after the bike's been parked for four or five days.

I don't completely agree with me either, and particular, agree with the your point about the dealer telling alibaba his problem is normal after more than one trip.  The answer there is either get the bike to a more capable dealer or get DNA to send a factory rep there.  Either way, DNA should know what is happening at the dealer.  Then, if that fails it is time to do what you need to do.  As a general rule, if you need to tell the tech how to fix your vehicle, you are in the wrong shop.

Someone on this board was having a warranty problem with his superbike that should have been resolved by the local dealer.  It wasn't happening.  DNA transported the bike to another shop at no cost to the customer.  The second shop resolved the problem in a reasonable amount of time.  Anyway, looking at the last post, it seems like all is OK now.
