Light tower genset in my bus, will it work?

[all2go]

All help and constructive criticism is welcome. I got a good deal on a trailer mounted Kubota powered light tower at an auction and would like to use it in my bus. Look at the Roadwork and Heavy Equipment auctions in your area, lots of good stuff fairly priced. The light tower was rolled so it came without the lights and pole. The winch and mounting is still there and looks great for a wind turbine mounting later. After getting all of the bent sheet metal of the enclosure off of it I changed the oil and radiator coolant and it fired right up. It seems to have low hours (1500) and puts out 125-130v on each leg and 250v on both. It is very clean and looks new now the wreckage around it is gone. It has a sweet little 3 cylinder Kubota diesel engine that says D-905. After looking it up on the Kubota website the engine seems a great choice? It looks like a Boss model BTK64MH light tower with a Newage 6 KVA generator head. No stickers or ID on the gen. head anywhere. Just the name Newage. Info I could find on the internet is, 60Hz, 1800 RPM, 240 volts, single phase, 25 Amps Base Rate, Continuous rating, and I don't know what PF: 1 means and Ex. Volts: 48 must mean exciter ? Anyway, now I would like to ask if someone could take a look at the wiring diagram I have made of the control box and tell me which way is best to wire it for use in the bus. If it can be used in the bus? I have attached the diagram. I can not find out exactly which generator head it is at the Newage site. Because it is transformer regulated I think it is this one:
STAMFORD RANGE
Transformer controlled synchronous a.c. generators
The STAMFORD range of "series 5" transformers controlled a.c. generators range from 6.25 kVA to 88 kVA.
This robust range of generators feature superb motor starting capabilities (1 HP per kW).
The voltage regulations for the series 5 generator is + 5 % at 0.8PF.
TRANSFORMER CONTROLLED : BCI16 | BCI18
A range of 4-pole, single or 2-bearing transformer controlled generators designed for very high motor starting loads (450 % for up to 7 seconds) where fine voltage regulation is less critical.(that worries me)
Engine adaptors to SAE 1, 2, 3, 4, 5 & 6, and coupling discs to SAE 61/2, 71/2, 8, 10 & 111/2, are offered on the BCI versions.
Dedicated adaptors for Lister Petter Alpha and TS/TR engine ranges are available on the BCAI & BCLI.
Windings are specific to output voltage (single or three phase).
Voltages available range up to 480 V.
IP23 enclosure protection is standard.
BCI 16 – 3-phase 4 pole 60Hz 7.8 - 17.5kvA
That was found at http://www.newage-avkseg.com/english/content/030101_stamford_0301.html and at http://www.newage-avkseg.com/english/content/download/newage/manuals/bc/BC168-184English.pdf

I can mount it with no problem in the A/C bay if it will work... It does not have an automatic voltage regulator it has a transformer, would I have to add an AVR??. There is one light tower I found listed on the big auction site (bidding closed already)just like it, item number 150051835005. There are some good pictures of one exactly like it.

I also bought a SW4024 inverter with the SWRC/50' remote and a Surepower model 522RB 24/12 100amp Equalizer to hook up when I get some batteries for the house bank. I need a panel and some other things...any suggestions as to which direction to go in setting this up would be appreciated. I know most of you will tell me to go straight to an electrician but I would like to do it myself. It can't be that hard if one is very careful, follows good advice, and double checks everything before putting power to it.
Thanks,
Andrew.

Andrew, it's very possible that more information might be available from Onan since Cummins switched to the Stamford-Newage generator end for a few years. In the early years Onan built a 4.0KW generator set with the Kubota Engine and it was Model 4.0DKC.  They also built an 8 KW model which was 8.0 DKD. 

Yours seem to fall in between the above two but it wouldn't surprise me if it might not be an 8KW...simply derated to meet this Mfr's. specs...it wouldn't be the first time that was done.

There's nothing wrong with Transformer voltage control...while it might not hold the voltage as close as a solid state regulator you need to remember that this genset was spec'd for an application where voltage control wasn't that critical.  If it will work for you...go for it.
