Question about Piaggio Motorcycles
Piaggio X7 125 , the batter y does not get any electricity, when I start the scooter at the battery yu still only read 12.4 V and does not get any higher if you accelerate. I assume is the stator or regulator or the alternator. HOw do I know ?
The batt may be old or has bad connections--must alwaays read 12.6v--alternator may be worn--the brushes in the rotor--git a repair manual for that bike

Your charger should be putting out 13.0-14.5 volts to keep the battery charged. Otherwise its running off the stator sometimes and the battery at other times depleating the battery. The voltage regulator could be bad or the stator could be bad. try swapping the volt regulator first and start from there. Also a battery that has been depleted should be sufficiently recharged before using it again.

Check the rectifier, its responsible for charging the battery when running, the fuse too, however the rectifier if it can not be repaired, better to buy a new one......................sodeep

your voltage/reg. can be tested in a couple different ways check ground res. check res. then revs. bias on diodes you have ac in dc out it sounds like you may have a diode gone bad allowing ac curent to flow causing the wires to get hot

I have a '07 C90T.
I have just replaced my stator. I replaced the reg/rectifier earlier this year. I replaced the battery one year ago in October.
I firmly believe what started the problem. Two guys that I told I didn't need help, but they pressured me to let them help. They hooked a battery backwards to my bike. A lot of people believe that's what shortened the life of the rectifier and stator.
But keep this in mind. The connections for the regulator/rectifier are not waterproof. I had done a lot of rainy riding and I first found a burnt connector on the discharge side of the reg/rect. My mechanic told me I needed to replace the reg/rect so I did but I soldered the wires and made them waterproof. I didn't do this on the stator side of the reg/rect and a few months later, when the bike quit charging again, I found that connector burnt, so I cut it out and soldered and waterproofed it.
Two days after we got back from a 700 mile round trip to Red River, NM, my bike quit charging again. This time though, I have a voltage meter on the bike, so I was aware of the problem before the bike could strand me someplace. Get one of those btw.
When I checked the old stator after I replaced it, I found the stator good but the pulse signal generator bad. It's required that you replace both btw. You have to, they are joined at the grommet.
Ok well, the battery cost $60 last year and I replaced it myself.
The reg/rect cost $140 through my mechanic and I replaced it myself.
Got the stator online for $173 shipped and they advertise a better stator that puts out 20% more power.
Not counting little things like solder, tape, heatshrink and such, I'm out a little less than $375 on my charging system.
I hope it's a done deal.
Again, some think the problems began when the battery was hooked up wrong, but I lean to believe the sub-standard Suzuki connections may have a hand in this.
Hope this helps. . . Joe
