Battery went dead while riding. changed regulator. charging now but stator wires getting hot is that normal?

yes it is the wires from the engine case . they get hot and then the regulator gets hot yes it is the wires from the engine case . they get hot and then the regulator gets hot

By hot, do you mean too hot to hold your hand on the wires or the regulator? Have you made any electrical additions to the bike? Have you changed the main breaker to a higher amperage? According to what I'm getting on this end, you bike is a "full dresser". These bike do require a large amount of current but everything was designed with this in mind at the factory. The regulator may get warm but shouldn't get hot.

If you haven't changed the main circuit breaker, the current load on the bike should not be too high. If the current draw gets too high, the circuit breaker will trip. But, the circuit breaker is designed to protect the wiring harness like it is in any vehicle. If you add electrical devices to the bike to bring the current load up to just before the circuit breaker trips, you're running the bike on it's edge of burning the harness up. Everything electrical gets hot but mostly the stator. The stator is inside the primary where you can't get to it to see just how hot it is getting. I've seen hundreds of them that have run hot for so long that the enamel coating on the wires had become brittle and cracked resulting in a shorted stator.

If you've added a lot of extra electrical equipment to your bike, you may wish to consider going to an aftermarket alternator system that has a higher current output. But, let's see how long this one last first. If you're not blowing fuses or tripping the main breaker, there's nothing I can tell you that is "wrong". Your bike simply has a lot of electrical equipment on it whether or not you've added anything.

Good luck
