Well guys, after a (almost) great solo trip of more than 1400 km on last weekend, when missing only 200 km to my home, the bike has stopped, entering to a gas station while idling. No lights, no starter motor, no nothing. Today I decided to remove the tank to see what could have been the cause of the first road fail on 12 years of my beloved ZX11, and I found this: View attachment 23017 View attachment 23018
I think I was lucky that the poor Motobatt doesn't explode under me, or that the failure doesn't happened in the middle of nowhere (it was a real possibility), this failure could be the result of a faulty voltage regulator that cooked the battery ??

Ps.: I forgot to say that all fuses are fine, it's all I've checked last Sunday.

Purchased in September 2021, and installed a few months later 馃槶馃槶
I thinking the same thing. Faulty regulator. Let us know if that's the cause of the issue.

Yep, batteries can do this. Regulator overcharging or failure within the battery itself. You can measure voltage across after you buy a new 1 & get the bike running again to check charging numbers. Dont tear apart that alternator just yet.:cautious: My money is on battery failure/defect, considering point of manufacturer :oops::rolleyes::D
I would be surprised if it was the battery

Ok, I suspect that it has to do with Jacksonville...
I've just talk with a motorcycle electrician and he proposed me to put an external car voltage regulator, the original here is totally unavailable and maybe it's a fine solution to have an easy part replacement. We should find a proper place to install it.
Anyway next week I'll take him the bike and he will check what really is the problem. Tomorrow should arrive the new battery, I will connect it and see if at least the lights turns on...

ps.: all newer bikes have the voltage regulator EXTERNALLY, why this had to have it internally ??
I speculate that it was to reduce the engine package. Stator/Generators are smaller.
