Q:I have a buffalo tools 2000 watt generator i have been rebuilding. I have searched for a wiring diagram to help but no luck at all my question is about the wires that come out of the section that generates electricity. Outside of all the resets and switches coming right out of the back of the section that creates electricity has 6 wires coming out. Four are hooked to two different plugs two in each plug one set is red the other blue and the last two wires are separate black wires i would think are negative/ground wires i am looking to know what the red wires and blue wires actually are dc/ac volt i imagine just would like to know for sure don't want to blow anything up and help even guesses will be greatly appreciated.

Only one way to know for sure, Run down to Harbor Freight Tools and purchase a 7 Function Digital Multimeter for $3.00 and test the wires for voltage and if they are grounds or leads.
