From the solenoid to the battery. And also connected a new ground. I left the original ground cable in place and connected the new one to one of the bolts in the clutch cover. After measuring with a multimeter this was the best one I found. I used 16 mm thick power cable that's normally applied in cars. Twice as big as the stock wiring with huge connections for maximum contact. When I tried to start the bike it fired up like never before. Waaauw. Measured the battery voltage at 3000 rpm and read 13.7 V on the multimeter must be enough. I didn't bother to measure the regulator, cause the charging system seems to be working just fine. Took the bike for a spin around the block, stopped, shut it off and started right up again. Before the cable transplant , even getting it started with a warm engine was a hassle. Now you can really hear the starter click without effort. Also tested at high speed/revs, the rev needle doesn't jump up and down anymore. The dashboard light doesn't flicker anymore. Well, juuuust a little bit, but not more than it should. The clock didn't jump to 00:00 anymore. So I guess the faulty ground, corroded connections and the original wires were causing most of my problems. Luckily I have a week off from work next week, so I got all the time to test the bike. I even think I'll put the fairing right back on tomorrow morning, if the bike starts at first attempt after a cold night in the garage. It's sure a good test to build my confidence back up. Quite important if my bike should get me to work every morning. Thanks again for all the advice guys. I hope I'll still have good news in 3 or 4 days, after I properly tested my red fury. For everyone else who has read this thread. Keep your connections clean and change your stock wiring to bigger wires even if you don't have starting problems (yet)!,It does sound like the battery may not be holding it's charge very well. If it's not very recent it may be due for replacing. A 10W40 oils should be ok for both winter and summer and is what is specified by Ducati for temperatures down to -10C. Although a 5w40 might give the starter an easier time, I suspect that the real culprit is the battery.,,,

Charging problem


stopped for lunch back on bike it started fine. About 20km later I heard the engine revs on my speakers running autocom of the bike the speedometer started going mad jumping from 30km/h to 220km/m, all over the place. The last time this happened was in France and the bike did not start again, battery was flat, bike shipped back to Ireland. Back in Ireland the dealer kept it for few days, battery was fine just needed to be charged, could find no other problem with the bike. While this time I rode straight to the dealer, about 20km away. When I stopped the bike was dead, no power. They did a test and said the regulator is faulty. Was waiting for new one from Aprilia but it did not arrive today so they took one from a new bike. The bike is charging when reved but does not want to charge at idle so they need to go fishing for the fault. It now also seem my clocks are broken as a result of al of this. ,Check to make sure that all of the chassis grounds are free of corrosion and properly connected. I have never had an issue with charging at temperatures ranging from below zero into the mid/high thirties (Celcius). Even at low speed you will be turning 3000-4000 RPM which should have the charging voltage between 14-14.5 V. Put a multi meter on it and see what voltages you are getting at different RPM's,,,
