    Did the generator ever work in the coach? If so, what changed? Was it just worked on (wiring, generator). Does your coach have an inverter? Is your transfer switch manual (move a switch by hand, or plug cord into outlet for generator) or is it automatic?

The wiring diagram for the generator is pretty simple. You have three wires coming out, White/Green/Black. The black is the Hot, White is neutral, and green is ground. If the generator is running and you do not have power at the black wire, the problem is in the generator. Check the circuit breaker on the generator for OK. Make sure that power is passing through it.

There is a transfer switch that switches from gen power to shore power when you activate one source or the other. That's where you need to start. It automatically should switch to one of the sources when you plug in or start the gen.

If you need further help, I’m available over the phone at

First you have to check(visuel & measure) on the excitation system ( thats include the rotor ), when you have problem there, you won't get voltage on the generator(stator)

What is the general specification of Genset 20kv?

Generally 20 Kva power generator can produce more power. The voltage used in this 20 kva generator is 3 phase with frequency 50 Hz. 20 kva generator engine is already very enough for use on buildings that require large electrical power or public places such as shops. According to me HARGEN provides the best high quality genset.
To fill the fuel tank to the full required 62 liters of fuel in order to use this 20 kva generator engine with more leverage.
20 kva generator engine is also issued a noise that can reach 61.7 db or can be heard up to a distance of 7 meters away from where this generator is located.

What do you need to watch while buying Genset?

There are several sites where you can get good collections of Genset. But before buying it from any site you must undergo through their latest reviews mentioned on the sites.
Before you buy a generator you must undergo through the following points:
1) Pay attention to generator function.
2) Note the type of generator needed.
3) Note the type of fuel used
4) Note the time period of tool performance.
I think HARGEN provides the best and cheap genset with high quality. They use quality steel materials so that the durability of their products remains unquestionable.

How does the wiring go from the own generator to its battery and then to electric panel

the ONAN generator only charges its own battery that it uses to start the machine,the generator itself is grounded with a 6 ft copper rod that is driven into the ground and secured to the ground strap of the generator,the wiring from the generator goes to a transfer switch that is installed ONLY BY A LICENSED ELECTRICIAN! DO NOT ATTEMPT THIS YOURSELF!,the switch is hooked up to your main electric line at the meter and to the breaker box,when the switch is used,it shuts off the main electricity from the company and opens the circuit to the generator is the transfer switch,it can run everything up too 100 amps in your house or only 1 thing like your heat.

Are the wires in a Onan gender numbered in the panel box cause their all white in color and all disconnected help me with a dummies version diagram please!

I believe you are asking about an Onan generator in a motor home? Search for your model number on generator, then go to the Onan website and look for a pdf download of their wiring manual. My dealer would help me with this for free, ask yours. Be prepared for $100/ hr if the dealer works on it.
