Might need a little more detail on what you are trying to figure out? the A/C side of the unit, or the control(start/stop)?

I only know the ev6010, but I am sure the 4010 is similar. It has 2 hot legs, and 2 neutrals, and a ground. but they are pretty well internally connected, so you can think of it has having just a single hot, single neutral, and the ground.

for my GM, I have the 50 amp outlet, so I have one of each of the hots that leave the coach connected to each hot leg of that 50 amp. the neutrals are wire nutted together and tied to the single neutral on the outlet, and then of course you have the ground leg.

you might have something different on your coach.


as for the control, there are 4 wires. there is schematics for the onan switches. and also for the pin out of the honda plug on side of the control box at the generator. I just matched function for function.

I am still trying to understand the question.

is there a transfer switch somewhere?

usually you plug the coach A/C cord, into either Shore power, or the generator. So the A/C wiring of the Generator is usually hooked up to a Female receptacle. and you would then plug the coach cord into that recepticle.


you confuse me as to the "battery".... that is 12volts DC. The honda basically has one 12v hot wire terminal, and you hook the big ground to the chassis, for starting power/cranking. It has ability to charge a battery, but that wire (smaller one going into a plug on the control box) should be cut on the harness, as it could potentially try to overcharge and burn the stator. use the coach Converter/charger and or the engine alternator to do any 12v battery charging.

this is detailed in Pinella power videos. if you are not familair with them, they tell you everything about the honda 6010 you need to know:

It may be 10f and you may have to wait for warm... but you ought to get your 'Fox N Hound' out and find out where those wires go.
