I haven't really ridden much in the past six months and I've started riding way more lately. So, I've been getting reacquainted with my 696. I have been noticing that it gets weird around the 3.7 - 4k rpm area. It gets choppy, kind of like when you hit the rev limiter, and sometime it seems like it coughs once and looses power for a second. I remember hearing talk about a 4k surge or something like that on the 696, but I have the Termis w/ the DP ECU, and I though that was supposed to get rid of the issues. Any one care to chime in?
You may have one of the 696 Monsters with reversed coil wires. Though wired wrong, the bike would still jive with the wiring diagram. Your dealer should have a service bulletin on this problem.
Thanks for the reply howie. I think the dealership I bought the bike from said they checked that. It doesn't happen all the time either. Today it only did it once, but yesterday it happened three times that I remember.
apparently the DP ECU's now keep the O2 sensors in the loop from what i've read.
That being said, probably still is a minor problem with the system trying to keep it lean.
for the coil issue. it's for the early production run numbers.
if you recently purchased the bike shouldn't be there.
but if it's an early 2009, doesn't hurt to get it double check by another dealer.
Raux is correct, this problem was on early '09s which were really late '08s An easy test is to check spark polarity using an analog (moving needle) volt meter. Hook up a voltmeter with the negative lead to the plug terminal and the positive lead to the block. Set the meter on the highest volt range. Crank the engine over (no need to start it), and you should see an upward swing of the voltmeter needle (don't be concerned with taking a reading). If the needle swings down off the scale, your coil is hooked up wrong. Reverse polarity costs about15% available spark loss. This will show up most where you are having the problem since you are still in closed loop.
and a constant 4k rpm cruising will result in overheating [bang]
I got my 696 in August '08, so it could be one of them. I'm not to thrilled with my local dealer so I'll try following howies instructions first.
Do you say to use an analog meter because it's easier to see it move, or is it too short of a time for the digital to get a reading. I'm just wondering if I need to find someone with an analog or if my dmm will work. I guess I could just try it when I get home and see if it works.
All you are looking for is the needle to swing to positive each time the plug fires, numbers don't matter. Off hand, I don't know what the results would be with a digital meter or if you could damage the meter.
Ok, so I finally got around to doing this test. I've only got about 14 days until my warranty is over, so I figured I better get on it. I think the polarity is reversed. I want to make sure I'm doing this right before I go into the dealership, that way if they say it's fine I can debate it with them.
I put the negative lead inside the the terminal that goes onto the spark plug, and I put the positive lead onto the tip of spark plug. Then I cranked over the engine and the needle dipped downward off the scale, instead of swinging upward.
That is the correct way, right?
if you do both coils you'll see one go the opposite way
You may be referring to the stuttering that all 696's have when you are at a very exact rpm somewhere around 4k. Part of the stock ecu's fueling problems. Both of the 696's I have ridden were exactly the same with this issue.
DP ecu/re-flash solves this.

Is the problem when they both go negative, or is one cylinder supposed to go a certain way? I have the instructions for the wire swap, maybe I should just tear it apart and do a visual check.
Swap the wires and if it runs better you are golden. 4K RPM cruise is significantly worse with reverse polarity.
Let me start off my saying that I don't have a 696, I have an 1100. I am kind of surprised that cruising at 4k will cause the bike to overheat. For highway speeds, I would think you would need to be even higher that 4k. Is this something you have experienced?
the reversed coil wires created a misfire at 4k causing the overheat.
Thanks for the clarification. That makes a lot more sense.

Wait, when I'm cruising at 4k my engine hesitates and loses power. Is this the normal 4k rpm hesitation or should I check for crossed wires??

Yes.
yes get your coils checked and yes there is a pit in the torque curve around that area but not enought to cause hesitation like you describe just a slight loss of umph at that range
I did the coil wire swap this evening and went for a ride around town. I don't think it was worse, but I couldn't tell if it was better. Before, if I was cruising steady, somewhere around 3.7k rpm it would do these little surges, it would speed up for about a half second, then slow back down, then speed back up, then slow down and so on until I changed the throttle position. It didn't seem to be doing that tonight, but then again I don't know the exact rpm where it happens. I'll just have to ride the Monster like I normally would and hope I know it good enough to tell if it feels different.
you confirmed you had the problem then did the swap?
I'm not sure how to actually confirm the problem. I'm going with howie's suggestion of doing the swap and seeing if it gets better. If I know it's running better I'll leave it. If I can't tell or think it's worse, I'll revert it back to the original way. I'm pretty much hoping that one way will be noticeably worse to me.
Look at the date of manufacture on your frame, if it falls between
ZDM1RADINX9BOOO065, 29th February 2008 & ZDM1RADINX9B011020, 16th September 2008, then you're affected.
PM me with an email addy & I'll send you a pdf file that contains directions on how to check for reversed coils. It shows the color coding of the wires. It also explains how to correct it. The wiring diagram in the original manuals was wrong. This one has the corrected wiring diagram.
I'm not sure about the date of manufacture, but my VIN falls in that range, closer to the 65.
FYI, if the coil wire issue has not been fixed (sounds like it hasn't) I would also suggest verifying if the other major recall for the wiring harness was ever addressed. There is an issue with the routing of the wiring harness around the vertical cylinder. The harness was actually melting due to this. My bike was also affected by this. I've pasted the recall info from the NHTSA website below. The Ducati recall number is in the NOTES portion at the bottom.
Make: DUCATI
Model: MONSTER 696
Model Year: 2009

NHTSA CAMPAIGN ID Number: 09V142000
N/A
NHTSA Action Number: N/A
Component: ELECTRICAL SYSTEM:WIRING
Potential Number of Units Affected: 1755
Summary:
DUCATI IS RECALLING 1,755 MY 2009 MONSTER 696 MOTORCYCLES. THE MAIN WIRING HARNESS MAY COME IN CONTACT WITH THE VERTICAL CYLINDER HEAD AND EXHAUST PIPE POSSIBLY RESULTING IN DAMAGE TO THE MOTORCYCLE AND A POTENTIAL HAZARD TO THE RIDER.
Consequence:
ANY DAMAGE TO THE HARNESS MAY LEAD TO LOSS OF FUNCTIONALITY OF THE MOTORCYCLE'S LIGHTING SYSTEM OR AN UNEXPECTED LOSS OF ENGINE PERFORMANCE, AND THEREBY INCREASE THE RISK OF A CRASH.
Remedy:
DEALERS WILL CHECK FOR INTERFERENCE BETWEEN THE MAIN WIRING HARNESS AND THE VERTICAL CYLINDER HEAD AND EXHAUST PIPE. DEALERS WILL REPOSITION AND FASTEN THE MAIN WIRING HARNESS TO THE FRAME FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN DURING MAY 2009. OWNERS MAY CONTACT DUCATI AT 800-231-6696.
Notes:
DUCATI RECALL NO. RCL-09-001
The funny thing about this 4k hiccup is that it has exsisted longer than just the 696.
When I got my 2007 695 it did the exact same cough at 3700-4000rmp.
i ended up getting the DP ECU.
I would have expected that after so many years, they would have cured the fueling issues.
the fueling "issue" is intentional on their (Ducati's) part. It is how they get the bikes to pass EURO emissions testing.
Thanks for the the pdfs and the heads up on the wiring harness recall z0mb1e_DUC.
I already took it in for the harness recall.
