GuysHere I am, mired down in my experiment by a 120 /240 volt ac generator, that in spite of rotating the shaft at 3600 rpm , puts out nothing.Oh I flashed the contact rings with 15 volts ac, alright.I did research to some extent on the internet.Seems this can happenThe stater coils are perfect.The rotor coils are also perfect.The bearings are as new, tooThere are two brushes that ride on the slip rings they are fine, too.That leaves two componentsA little black epoxy encapsulated box,and a relay switch with120 v. ac coil operating a single pole switch.Essentially, six wires emerge from the stator coil. Two come to the voltage regulator. Switch on/off? The other four seem to go to the coils, or get grounded to the frame.Does anyone here, in our group know about small kohler construction generators when it comes to taking them apart?The internet goes over fixing one with my symptoms. It was the voltage regulator, that needed replacement.No problem! I'll just buy another.$300.00 US? WTF?You know what I am trying to do with this flywheel experiment.I am driving an AC motor to turn the flywheel , first, from power from the grid to the motor. When the motor is up to speed bingo! I switch over to the ac generator output from the grid driving the motor to the generator driving the motor with the inertia of the flywheelI don't know if it will work, that's not the point, because before I can do this, the damn generator has to run. It doesn't when I turn it separtely at proper speed from the grid.I don't want to spend $300 US for a regulator from Kohler.Do I even need a stinking regulator?Can I meter everything and adjust the rotor electromagnet with variable dc?There are five pins on the regulatorTwo go to the brushes for the slip ringsOne goes to the relayTwo are AC from the stater.It is a potted black box.The brush wires are marked + & - , so there must be diodes in there to rectify the ac? The orange wire coming fron the potted box goes to the relay primary coil, which then gets grounded to the chassis from the other pole.Something must be shutting off the relay when voltage reaches a certain voltage.Since the generator is slaved to the drive motor through the flywheel, why can't the experiment be mannually regulated?Can I just put a variac on the ac, coming from the stater coils into the regulator, rectify it, and then send it to the electro magnet rotor?Sorry for the long emailCheers Warren
