And one last post in reply to your thoughts as to upgrading to a 500W resistor I read all the previous posts and in post #1 you posted two data sheets for two different AVR’s. A VR6e3-4A/UL and a EA350 which one do you have actually installed?

I am not 100% sure if this is your wiring diagram, the Volt Gauge and Frequency gauge are connected in Parallel to L1 and N which would be 120VAC In this case your Frequency Gauge is toast

not sure of what to make out of your analog frequency gauge.

That’s what power resistors do, they get hot. That’s why they are called power resistors. It’s basically a heater. Mount these type of resistors on a 16ga or thicker sheet metal and make sure the location of this puppy is well ventilated, far away from anything flammable, gas or diesel and...

Your wiring diagram looks ok to me. I would move the #4 Terminal with the fuse to the other side of the 15 Amp Breaker. This way your field wont collapse when the 15 Amp Breaker trips on the load side. The backfeeding of the exciter coil should not pose a problem since one leg is Neutral /...

@Skyhawk13205 Luck be a Lady, what is your measured DC Resistance of the exciter and field coil, without anything connected to either one ?

@Skyhawk13205 Then if I understand you correctly, you actually have this wired up like this: The exciter coil is then powered by the top battery in your diagram and gets about 12V when you close your exciter switch which is most likely a momentary push button type switch. Did you leave the...

You are lucky that you are still alive and can post your findings. One day someone here is going to kill him / herself with these generators There is several things wrong with your wiring diagram. First, your exciter coil is connected directly to 24 VDC at all times Second, your exciter...
