The charging system is "magnum inverter/charger". Its a pretty slick system.

36 is a mechanical fault.... Usually in diesels you want to check first the fuel (condition, filter, etc) next would be air, and then compression (but its never compression in a kubota, thats why kubotas are the best).

For my case, the computer was not sending power to the 12v lift (low pressure) pump causing the engine to starve. Hence the reason it would run for 5 minutes or 2 hrs. The computer would just decide to go on a vacation and not turn on the fuel pump.

I looked around and found that the 'only way' to fix would be to buy another computer at the price of $1200... AND THATS IF YOU COULD FIND ONE! NO WAY JOSE!

My solution (which I'm sure some will cringe with) was to wire the fuel pump directly to the switchlight on the start/stop/prime switch. Such that whenever the switchlight is illuminated, the pump will be on... All the prime, start, stop functionality works from inside the bus and on the genset itself. The auto gen start system still works as well. The only downside is the pump will run continusouly when the genset is running... Which isnt an issue because theres a fuel return line for excess fuel. The fuel pump is one of the 'clicky-clacky' types. Very basic (2 wire, 12v) and can be found at NAPA, just make sure it works with diesel.

Please if you have any questions REPLY TO THE THREAD so that other people can benefit from our diagnosis. Thank you.
