Hi guys, just curios, what will cause a regulator to fail? Age? Over volt/amp? what?

I had some regulator issues since I first got the bike, till it eventually just stopped charging. Got the thing replaced with a sourced part, second hand. Yesterday It broke again, or so I suspect... I don't really have the tools to check these things so waiting on a mechanic to tell me the news...

But what bugs me is that with the original regulator, I pushed the bike pretty hard, for about an hour, hour break and then for another hour, and it was fine months after that, then, the other day I took it out on the freeway again, pushed it a bit( for like maybe 2mins), and the next day the thing wasn't charging. Battery is new...


I honestly don't have a clue on how a regulator works, just know it regulates power and is responsible for keeping the battery charged... now what I'm wondering is, how does something like that break... I mean, does it have capacitors or something that only has a limited lifespan or something? can the bike essentially produce too much current for it to handle? burn it out?

Please let me know what you guys think?

Oh and by pushing the bike i mean going like 150km/h

Any advice would be helpful.... Getting parts for these CB750s is a mission here, and most parts are secondhand.... unless i import

I so wish I could just be done with studying so I can have time and money to get a proper workshop together and fix my own stuff... and learn off course...
