The OEM regulator on these bikes is some bizarre Ducati paraphernalia that is RATED to regulate charging to 15 volts.But a bunch were failing even at that ridiculous rating and overcharging to a tune of 15.2-16.0 volts.Jay, Cam, and I replaced four regulators between us on 2013-2014 bikes in our garages alone and there were reports of more.We went with a rather standard mosfet type regulator and now our charging systems regulate to the low 14's as gawd intended.I believe that Todd at Guzzitech saw a few that were spiking even worse and thinks that it fried one or two ECMs as well.So I'd be curious how your charging system is regulating.But I would probably be starting with the usual suspects - cables/grounds/connections.
Are you sure the problem is with spark? Yes, the R/R may well be over charging so that's worth checking and changing just as a long term precaution. You say the engine started missing and then would quit running. I'd look at fuel problems. It's possible your fuel filter has sprung a leak. Remember that the OEM filter is half metal and half plastic. It's also possible that the filter is clogged. Finally, water in the tank could cause these same symptoms. Water molecules are large when compared to fuel and can actually block the tiny injector holes (per my diesel mechanic friend).Peter Y.
Thanks Kev, I remember a thread fest on regulators. Are you talking a NAPA part regulator or a Big 4 Japanese bike regulator? Both of which I should be able to buy off the shelf here in Yukon.Will do the cable/ground/connection routine but I'm fairly confident everything is tight. I replaced spark boots and leads about 5k km ago.

2013 V7 does not have a voltage display.
Oh, I saw both 23 and 26 inputs labeled Battery on the dash keyThen a cheap meter or Voltage display would be essential I think
Last ride of last fall my 2013 V7 went intermittent while I was riding. The motor would just stop running while I was moving. Then it would kick back in for a while. Getting home in 4th gear to keep the revs up and even that 'trick' failed in the end and I coasted into my driveway.
Kiwi-Roy, you wrote about relays for injectors in another thread (V7 Starts then cuts out). Have these relays been problematic? And with the injectors showing life in the software... are the relays relevant to this part of the conversation?Now that I'm connected via GuzziDiag; which features in the drop-downs would be useful to look at? Thanks as always.
Last evening I reconnected the tank then turned the key to pressurize the fuel system. The bike fired to life for about 15 seconds before sputtering to a stop.It appeared that pressurizing the system pushed fuel into the cylinders. As soon as it was burned off the fun stopped. Does this make sense? And now that it is April: we are expecting five inches of snow to arrive today.
......................What you need to figure out is WHAT killed it at 15 the seconds mark - some circuit opened - was it the pump, was it the ignition, was it a relay? etc.
< said smart stuff, then fixed it so it was smarter >
Another thought I had which is probably better answered by someone other than me: Could the crank sensor be failing? The ECU would shut down the spark if it thinks the motor isn't turning. Just a thought...John Henry
And a good thought too, my $2 relay light AKA "Go Winkie" would flash back at you, Hahha The light would be tucked away out of site and just pulled out for times like this, I had mine under the seat.
