I'll get back to you on that stator
Edit....can you explain that #4 scenario to me?
Hizzo and cegodsey, see if I learned my lessons from this summer in order to answer the #4 scenario:
The battery is DC and all of the electrical components on the bike suck up the juice from the battery as the bike is running (or not - like if it's sitting in your garage and you forgot to turn the key to 'off'
). The only way to recharge the battery is to generate AC (stator), convert it to DC (rectifier), and then store it back in the battery. If the battery isn't holding its charge, the r/r is working that much harder to try to recharge the system; given where it's located on these bikes (under the battery box, where it can cook), the harder it works, the hotter it gets. And when the r/r gets fried, then "something unimaginable happens to the stator." Well, I think the current from the battery that normally would go through the r/r to the stator is now unregulated, and thereby theoretically sends an infinite amount of current to the stator (thereby blowing it).
That said, the regulator/rectifier set-up is both a "push" and "pull" system, right? It controls the flow of DC from the battery to the stator (push), but also converts the AC flow from the stator back to the battery.
Okay, now someone can correct my folk theory of how our 750 charging systems work (but that's what I took from my summer repair lessons).
