2007 Monster S4RS Shutoff While Riding... Charging System?

What do you think about this?

While riding my 2007 Ducati Monster S4RS to work today it suddenly, without warning, shutoff. The engine came to a stop, the gauges turned off, the lights went out, and the speedometer is stuck at 55mph. Trying to restart the bike the lights are turning on and I heard the fuel pump prime, but the gauges are not. I tried to restart it a few times and afterwards it didn't seem to have enough power to even get the fuel pump to prime or turn on the lights. Tried to push start it and nothing. Ultimately I had a buddy pick me up with his trailer and tow it back to his place for the time being.

Given the circumstances it seems to be the charging system, right? Perhaps the regulator rectifier? I imagine that I was able to get as far as I did this morning on battery's power alone, but because the charging system isn't working properly I imagine it finally died on me once the battery ran out of power. I'm worried how much this might cost.

Yup, sounds like it, but more likely the stator. Charge your battery, then test the charging system.

Print out the PDF and start testing. Same thing happened to me when my R/R went out. Replace it with a mosfet unit and never worry about it again. Be sure to get rid of the horrible plugs that the R/R connect to the bike with also. Look at those and if they are brown its another sign your R/R went out.

I would bet regulator/rectifier before stator. I've replaced several R/R on my modern Ducati in the last couple years. Replaced with Shindgren Mosfet units and they run a lot cooler.

I've changed way more stators than RRs.

I've changed 400% more R/R and never a single stator in my year models 2000+ Ducati, that would be 4 to 0. Including, but not limited to, my 2008 S4RS Tricolore.

What we have here folks is an old fashioned pissing match. Get some popcorn and tune in for the details. Keep us posted.

I've changed so many stators, I can have it changed before the motor makes a full revolution.

Plus, my dad can beat up your dad.

Seriously though, I think my stator to rr ratio is 5:2, and the RRs only needed to be changed because 1 was as a precaution the customer wanted, and the 2nd a wire made contact with the frame and charred the connection, but the device itself still worked; I spliced the wires until my new part came in. This is in Jap bikes and my 1100.

I've had so few problems with RRs, I actually thought they were a pretty bullet proof device for years until I started reading about other people having issues.

Awe this thread makes me sad.


You mention that your dad can beat up my dad. That means you've actually met my dad. If you ever see him again, tell him I'd like to meet him.


I so wanting to hear back from the OP so we can start the diagnostic tests and help him determine which it is. Probably just the ground wire came loose at the battery or frame.

Update:

I found a #5 fuse was blown, replaced it, and immediately the replacement blew. I got a multimeter to do testing and the battery is reading 13.34 volts.

Do you guys know what the fuse in the 7 position in the fuse box powers? I have to imagine it's for my gauges and or ignition switch. Would that stop the bike from running?

Do you know if the ground for the circuit powering the gauges is the one pictured right on the left side of the bike bolted to the frame or is it elsewhere?
