Unless the SX460 has a frequency adjustment, (I am not fully familiar with the SX460) I would suggest setting your engine RPM up a bit to 61-61.5 Hz then set up your voltage.
AGAIN...NICE INSTALL! Sure beats the heck out of the replacement costs of the OE regulator.
I have often wondered why Onan didn't duct cooling air or at least vent the top regulator house for cooling air.

Don't think there is much wattage dissipation in the reg. Between that and metal box doesn't sound like needs cooling air, I'm guessing ~ 10-15 watts max. Besides apply cooling air and you'll get all kinds of dust accumulation. Then with bit of moisture that dust becomes conductive.

There is a simple answer why Onan didn't do that. Onan did not want to disturb the mice that are/will be living directly below in the control box in the J series gensets.

I installed the 1/4 inch 3x3 angle iron under the 30 kw onan dda in the 7x14 enclosed trailer

For added security.. I used a grade 8 1/2 bolt through the angle iron though the 1/4 inch boxed frame on each end. and welded them in as well.. I don't think it's 2000 pounds will be moving.. unless a truck runs it over..

Next I need to install the floor tie downs for other onans..

And im.really thinking about putting in my 3 kw onan dsl diesel on the other side of the 63 gallon fuel tank.. would still be able to fit two ccks up front and a in in the back and be under the 4880 pound payload capacity.. just under it lol.. good thing this trailer has brakes on both axles.

I did not take any pics of them welded in... because it kinda looks like poo.. but.. laying on your side with less than 6 inches of head room and welding down, or up rarely does.. at least for me

The mig welds I see in your pics look great, but I guess they are not the welds you refer to by welding down. Do you mean upside down??? I too have problems mig welding directly upwards. Welding downwards and sideways not really an issue.

Spent money buying a voltage regulator from flight systems. Does that count as doing something to my green machine.

No not upside down but close.. kinda on my side.. kinda on my back..

The.welds you see were done inside the shop.. facing down.. I can usually weld ok going down if I can get the gun up higher than the bead.. but not if its below.. just does not puddle right.. maybe I need to turn the heat and speed up, or just turn the heat up.. but that would require crawling out from under it multiple times.. and I was not having it.. maybe if I get a forklift and can lift the whole rig up I can better them in the future..

Today, I setup all my gensets for a quarterly run scheduled for tomorrow. I am currently charging the batteries. All were not too bad at all considering the last time I started any of my gensets besides the JB was last November.

In the pictures below are the 2LK(not ready for running yet), 6.5NH, 7.5JB, 4.0BFA, and a 2.5AJ. It will be a fun night tomorrow running all these at the same time, but I need more heaters/load devices.

A bit O/T- not "to" my Onan, but "for" my Onan-
Gathering parts for a 10kW load bank/shop heater. I have a mobile home "furnace" that has (2) 5kW elements in it and a large blower. With a little re-wiring, I can make it switchable to 5/10kW for 240 volt sets and 7.4/3.7 for 208V.
