Was running well until one month after his warranty expired. After finishing up a long ride, bike shuts off...cannot restart, dead battery. Battery is replaced, bike fires up, no worries...That battery draws down, no start...indicates original battery maybe not bad, probably a charging problem. Local Ducati Mechanic replaces rectifier/regulator...original battery charged up and installed, bike runs fine. (spare battery now sits in garage) Couple of days later, son on bike on nice ride, about 45 mins in to the ride bike shuts off while at about 60 mph, 4000 rpm...instrument cluster freezes in that position... He pulls over and he hears whistling from under tank...lifts fuel tank, battery is extremely hot and is the source of the sound, he removes battery and places it away from bike... Bike recovered to house by truck. Would seem that battery was being over charged. Complicating troubleshooting is now, with another battery installed, instrument cluster will not reset, needles are stuck at 4000rpm and ~60mph. Could not reset with Red Key using the immobilizer reset process. BTW, found a pinched and grounded tail-light wire where the seat post pinched it into the locking mechanism bearing the wire. Any ideas on how to get the instrument cluster to reset? Ideas from there? Thanks,
