Got an 04 M620 here, and I can attest to the weird wiring issues on these bikes. Had a headlight that kept popping bulbs. Checked the wiring and one of the wires was so stiff that it felt like it would snap if I bent it at all. The odd thing was that it was nowhere near any heat source. My guess is that maybe some water got in there and caused the wire to corrode. That was about 8 years ago. Now that the bike is much older, I am expecting to start running into issues such as yours. Hope you're still riding. Thanks for the vid. And, if you haven't yet.. definitely put a fuse on that regulator wire.
Thanks for the video. Had this exact issue and your fix solved the issue for my 2001 monster. Was running great for about 6 months but recently starting to have issue of not enough spark/too much fuel. plugs wet, sputtering and dying on first quarter of throttle. Just wondering if anyone else has had this issue as well, or if there are any suggestions for troubleshooting? cheers.
Great video thank you! Quick question, I’m still testing as we speak, but I have the same issue new battery came in and started right up. So when you say you spliced those red wires, did you completely bypass the original connection that Ducati did from the reg/rec to the battery and spliced in your described connection or are you using both connections?
@@VroomBroomZoom gotcha, no worries! I appreciate it, my stator isn’t top notch health wise but the bike runs well now with the bypass connection you displayed. Those old wires really were choking the current. Bike runs a lot better and the battery finally keeps a full charge. Also changed out the rectifier looks like it was over heating a lot because of poor connection
My 2016 Monster 1200s headlight and rear light still on even when the key is off. This always happen after heavy rain (I unplug the battery before and took few days to get it back running normal again). I try to unplug the connection, meter, ecu, black box one by one and today I found it turns out the fuse (3A) for the ‘diagnostics’ will make these lights turn off. Any advice man?
Hi! Thanks for this! Was looking for a solution to a bad connection on my 848 but i ended up here. Seems likely this will be something that will come up on that bike as well as my monster 620. Pleasant watching! Br Per
Hola buenas,tengo un problema y me lleva loco.haber si alguien puede echarme una mano..tengo una monster 600 2001 y al arrancar arranca bien pero el cilindro trasero,el delantero no..si la mantengo en relenti un rato y acelaro un poco fuerte empieaz a funcionar coarrectament..bobinas y cdi estan biern podria ser el rectificador o esl estator..este perdio ..gracias
Many mc charging systems are the same as your Ducati’s. What I’ve found the problems to be are in the connectors and wiring size. The 3 yellow stator wires on my 98 Honda VFR are about 16ga. while the 3 yellow wires to the rec/reg are closer to 12-14ga. wire. If the battery has low voltage and one gets his bike started, the current flowing through the connector (stator to rec/reg) may have enough resistance (due to corrosion, poor connection, etc) to even melt the plastic connector housing! Also, a poor connection to the btry’s neg. post can overheat the attached wiring. But your video is informative, good work.
If I may comment about the different wire size found between stator and RR, then RR and bat. Stator to RR is AC voltage, and it do not require as large a wire gauge, where as RR to bat is DC voltage and the wire must be thicker. You can see many practical examples of the different wire size differences comparing AC and DC, in fact it's the smaller wire size (and higher voltage) of AC that make AC the practical solution for commercial power distribution. On motorcycle system you shouldn't worry about wire size on stator...but you SHOULD increase wire size from RR to batt (like done here) to overcome resistance, especailly when the wire become heat soaked. More heat in the wire create more resistance, which is why a cold engine bike might crank normally, whereas after ran and the wiring is super hot...struggles to crank. NEED MORE DC WIRE size
had this exact issue for my 848 evo 2011 but in my case the old rec reg when idle got 13.4 - 14.1 volt. when i twist the throttle to high rpm it can be 14.8 until 15's someting. so i bought a new rec reg it cost $25, i plug the new rec reg my 848 evo still have a issue the voltage so high.. for idle i got 14.5 - 15's when high rev gor HI voltage... any recommendation sir ? btw the battery is brand new
I’m only an amateur mechanic (very amateur), so take everything a say with a big grain of salt. If you’re getting a spike when applying throttle, I’d say your stator is the problem. You’ve swapped out the rec/reg, so unless it’s also faulty, is has to be the stator. 👌
my regulator was dead for some time and I thought it was a bad battery… then it wouldn’t kickstart and I was in the middle of the M25 ring of London on the way to a catch a ferry in Dover…had to have the bike towed, speedcharge the battery, and replace the regulator…they charged around 200 for it 😂 the towing itself was only 60… nice to hear you got the part for 25 🥲
I just taped on the starter with a hammer and it disengaged. The kill switch some times messes up. It relay o ly does this when its cold and dont want to start. So I keep trying g and since times the starter will get stuck
hello , my 2004 ducati s4r has a problem borrow me long time .can u help me fix it ? when N gear i push full throttle the rpm can go the red line quickly,but when i ride on street,if i push the throttle more than 1/3 ,my bike feels like cant breath ,no power and rpm can't go to red line ，i dont kown how to fix it ,wish your help .thanks a lot!
Good video. Thx. Take home message- electrical problems in older Ducatis are always in the wiring, until proven otherwise. 😉
Pretty much 😜

Hahaha, she’s long gone, I’m glad yours is still running. I’m still riding, Z900…..such an amazing bike. 😀

I am having the same issue on my 02
I just got these problems and the reg is smoking. Did you just repalce the reg?

So when you say you spliced those red wires, did you completely bypass the original connection that Ducati did from the reg/rec to the battery and spliced in your described connection or are you using both connections?
I'm sorry, I do not completely remember, but I think I spliced both. Don't quote me :P

Well done for locating the issue. 👏 From here, I’d say check out the forums, try a lower/higher rated fuse (but that can be very risky).

Thanks for your comments. Glad you found it potentially useful. 👍👌
Thank you. This may help with my 2016 1200 .
I think in the newer Monsters they routed the wires differently so HOPEFULLY won’t be an issue 👍🤞
Thanks for your video!
No worries 👌👌👌
hello do you know where i can find the ducati monster 2009 1100s wiring diagram to replace the speedometer dashboard
?
Your best bet are forums. Sorry I can’t be any more specific

That sounds like bargain towing compared to here in Australia. Glad you got home safe👍
SO I HAVE A 1999 M750 AND ALL OF THE SUDDEN THE STATER WONT DISENGAGE. I CHECKED THE RELAYS UNDER THE SEAT ANT THEY'RE OK. WHAT AM I MISSING????
Won’t disengage? I don’t get what that means
My 99 750 does that some times.
I just taped on the starter with a hammer and it disengaged. The kill switch some times messes up. It relay o ly does this when its cold and dont want to start. So I keep trying g and since times the starter will get stuck
What is the website?
