Charge Controller/Converter issue?
I'm new here, thanks for having me. I'm also new to RV'ing and have run into a confusing issue with a new to me RV I bought a few months ago. While hooked to a generator I noticed my box fan seemed to...

I checked my 110v plugs in the RV I found something odd, when I went from ground to hot I got 65V, when I go from ground to neutral I got 65V, when I go neutral to hot I get 120V.
100% normal when using a portable generator.. WHY you ask?
In electronics there is a device called a capacitor. and another device consisting of two capacitors called a "Capacities voltage divider" This is like a resistive divider in a DC circuit.
Now imagine the following DC hook iup
12 volt----100 ohm resistor--X--100 Ohm Resistor--Ground (Returns to battery)
The two identical resistors will divide the voltage so the voltage at point x (assumign no load) is six volts 1/2 the battery.
Well in an AC cucuit it works the same way with Capacitors
120 V Hot----||----X-----||----- Neutral
The || is the symbol for a capacitorl it is also how they are built
Two metal plates with an insulator between them
You have how many feet or ROMEX in your house on wheels
Romex is three wires side by side. the hot is on one side neutral on the other and ground in the middle
Makes a capacitive divider
HOW TO FIX
Bond the Generator outlet if it allows or make a special generator adapter with neutral and ground bonded.. IF YOU DO NOT KNOW HOW. Get help from someone who does.
