I need a wiring diagram as my son connected the battery wrong negitive to positive need to see what all is wrong

There is a fuse link at the Positive battery terminal wire. It will blow to protect the circuits if the battery is hooked up backwards.
It is a smaller gauge section in the wire that melts to save systems. any auto parts store has one

How do you remove the rotor on a sportsman gen154 generator?

The bolt in the end where the exposed bearing is a very long bolt.It goes thru the entire length of the generator and threads into the crankshaft of the engine. Loosen this bolt slowly but firmly since it will twist a lot before it breaks the threads loose. Once the bolt is out if the rotor doesn't come off easily, then give it a nudge with a rubber mallet.

Have a 4000 watt sportsman generator that will not produce electric i have replaced the avr what next

Could be lost exciter current. This is how to restore it - Connect 16 or 18 gauge wires to a 12 volt battery. With generator running, insert bare ends of wires into AC outlet - one to Hot, the other to Neutral. Insert and remove quickly. There should be a flash and power will be restored. If not, repeat until you get that flash and output current restored. Using light gauge wires is so that if you are too slow to remove them once AC is restored. they will burn out before the battery suffers from the AC incoming. Be quick and be careful.

My portable generator runs great but only produces 7 volts and 20 volts on each 110 volt receptacle and 20 volts on the 220 volt receptacle. any ideas on troubleshooting steps to find the problem part?

Assuming the speed is correct check the voltage on the rotor brushes during running (Caution) It should be DC. If you have low or no DC voltage then the capacitor in the end of the generator housing is bad, or the AVR. If you do have voltage then make sure the slip rings are clean and shiny, from there you may have a rotor or stator issue that needs carefull resisitance check
